-= Changes between the Supra 288 1.44-09 and the 1.440-012 ROM Code =-
26 June 1996 (ALJ)
1) Official release of 33.6 kbps support.
2) Corrected parsing problem with +MS command on some models
3) In products with MNP10 support the \Xn command can be used
to completely enable or disable MNP10.
\X0 enables MNP10
\X1 disables MNP10 (default setting)
When MNP10 is disabled, the -K1 command will allow the conversion
of a LAPM connection to MNP4 connection instead of to MNP10.
4) The default setting of S38 was changed from 20 to 5. This is
the number of seconds to wait for data transfer to finish after a
hangup command (ATH or DTR drop) with an error correcting link.
5) Corrected problems with hangup by DTR drop.
6) New v25ter commands added:
+DS V.42bis control
+DS=<direction>,comp_neg,dict_size,max_string
+DS=? prints command range
+DS? prints current setting
direction
---------
0 No compression
1 transmit only compression
2 receive only compression
3 bi-directional compression
comp_neg
--------
0 do not require V.42bis compression when
connecting
dict_size
---------
2048 V.42bis maximum dictionary size for
bi-directional compression.
4096 Maximum dictionary size for single
direction compression
max_string
----------
6 to 64 Maximum V.42bis string size.
+ESR Selective Repeat (LAPM SREJ) control
+ESR=<value>
+ESR=? prints command range
+ESR? prints current setting
value
-----
0 Do not use SREJ
1 Use SREJ if available in remote DCE;
continue without if not available.
7) S191 now works correctly to control ARA EQM bias.
Was disabled in 1.440-09 firmware.
8) Connection algorithm was further modified to improve connections
on all V34 products (with or without 33.6 support).
9) New result codes
--------------------
60 CARRIER 31200
65 CARRIER 33600
91 CONNECT 31200
95 CONNECT 33600
10) Added ANOTHER(!!) connection status command

11) Corrected onhook/offhook and muting funtions on some Voice products.
-= Changes between the Supra 288 1.44-07 and the 1.440-09 ROM Code =-
1) The method used to set the initial receive rate on V.34 connections
at the 3000, 3200 and 3429 symbol rates was changed. The new
method greatly increases the number of TSB37A lines that connect
at 19.2Kbps or above.
-= Changes between the Supra 288 1.44-04 and the 1.440-07 ROM Code =-
SupraFAXModem 288 = SUP1200 (External w/LED Display)
SupraFAXModem 288i = SUP1210 (PC Internal w/Jumpers)
SupraFAXModem 288i PnP = SUP1290 (PnP Internal)
SupraSonic 288V+ = SUP1330 (External w/LCD Display & Voice)
1) The +MS command was not returning ERROR when an illegal text
protocol entry was used. (eg. +MS=VFC didn't return ERROR.)
2) When displaying local or remote rate renegotiation requests
(S194.3=1) the LCD will now also indicate whether retrains
were initiated locally ("LocRetrain") or by the remote
modem ("Retraining").
3) When receiving single message Caller*ID packet the LCD was
not correctly displaying the received phone number.
4) S194 was not listed in the \S1 S register summary.
5) The three letter country abbreviation used for Australia and
Austria was "AUS". The abbreviation for Australia was changed
to "AST".
6) The ARA tables for 3200 and 3429 symbol rates were modified to
increase the percentage of lines that connect at 26400 or 28800.
7) Issuing an ATZ while off hook (either an incomplete dial command
or an ATH1 command) would not correctly go back on hook.
8) A problem that could cause the Sonic V+ to hang at the end of receiving
a voice call is fixed.
9) The ARA tables were modified to slightly increase the connect
rates on high bandwidth lines (3429 symbol rate) with moderate
noise levels.
10) Modified the AutoBaud routines to correct character loss at various
DTE rates.

PERFORMANCE IMPROVEMENTS
- V.34 Operation
Improved V.34 connection reliability on low bandwidth lines
and slightly increased data rates on higher bandwidth lines.
Fall forward, fall back and retrain EQM threshold levels
modified to slightly increase data rates.
Improved connection reliability with non-Rockwell based
modems at lower symbol rates (3000 and 2800).
Improved V.34 connection reliability with 2400 symbol rate.
Improved V.34 connection reliability over ADPCM connections.
- Country Settings
Korea added (which resulted in Norway being removed).
Switzerland call progress tone threshold changed to allow
detection of busy below -38dBm for the range of 375-550Hz.
Also fixed LCS operation.
Denmark country code changed to detect BUSY from 200-300mS.
Flow-control thresholds were updated to improve throughput.
NEW (& updated) COMMANDs and CODEs:
- $ dialing command can be used in addition to & to wait for
credit card billing tone. (per Microsoft suggestion)
- Added additional V.25ter command +ES.
Note: +ES=<R>,<O>,<A> is similar to setting the &Qn (or &Mn), S36, and
S48 registers. When +ES=<R>,<O>,<A> or +ES? is used S80.4 is set
(1). When &Qn (or &Mn) is used S80.4 is reset (0). These values
and S80 are saved in NVRAM via &Wn.
<orig_Rqst> 0 DIRECT mode
1 BUFFERED mode
2 V.42 with detection phase
3 V.42 with detection
4 Alternative Protocol (MNP)
5 Synchronous mode
6 V.80 Synchronous Access mode
<Orig_fbk> 0 EC optional, if no EC use BUFFERED mode
1 EC optional, if no EC use DIRECT mode
2 EC required, if no EC disconnect
3 LAPM required, if no LAPM disconnect
4 MNP required, if no MNP disconnect
<Ans_fbk> 0 DIRECT mode
1 BUFFERED mode
2 EC optional, if no EC use BUFFERED mode
3 EC optional, if no EC use DIRECT mode
4 EC required, if no EC disconnect
5 LAPM required, if no LAPM disconnect
6 MNP required, if no MNP disconnect
7 Synchronous mode
8 V.80 Synchronous Access mode
The +ES command is similar to setting &Q, S36 and S48. The
modem can take different actions when originating or answering
a call when the +ES command is used to set the configuration.
When a +ES command is used, S80.4 is set. This indicates the
modem will follow the +ES setting instead of the &Q setting.
When a &Q/&M command is used, S80.4 is reset. This indicates
the modem will not use the +ES setting. The current +ES
setting and S80 value are saved to NVRAM with the &W command.
- %Q1 Connection Information
V.32/V.32bis Connections these items are reported:
EQM (Same as %Q)
RX Level (Same as %L)
TX Level (Current TX level in dBm)
V.FC & V.34 Connections these items are also reported:
Far Echo Delay (Round trip far end echo delay in mS.)
Far Echo Level (Signal Strength of far echo in dBm.)
Pre-Emphasis Filter (Filter in use to normalize the lines
frequency response as per ITU V.34 specs.)
V.34 Connections these items are also reported:
Shaping TX (0 no, 1 active) RX (0 no, 1 active)
Non-linear encoding TX (0 no, 1 active) RX (0 no, 1 active)
Trellis mapping Type in use (example "16-4D")
SNR (Signal to Noise ratio measured during
the line probe, in dB).
Normalized Bandwidth (The -3dB roll off points after the pre-
emphasis filter is applied. This is
NOT the same as the usable audio band-
width since the signal has been heavily
processed prior to this measurement.
This range determines the maximum
symbol rate the line will support.)
Symbol rate (Symbols per second on the connection)
If the Symbol rate is below 3429 these are also reported
TX Carrier (LOW or HIGH)*
RX Carrier (LOW or HIGH)*
* If the symbol rate is below 3429 there are two
available carrier frequencies ranges. (A HIGH
range and a LOW rangecarrier and a low carrier.)
The actual frequency range of the carriers varies
with the symbol rate.)
- \S1 command prints the current values of the S registers.
- VFC connections are disabled if +MS=V32 or +MS=V32B are set
- S192 changed
S192.0: Fast SilentAnswer snoop
S192.1: Adaptive answer only looks for CNG not data carrier
S192.2: unused
S192.3: Transmit short TRN sequence
S192.4: Limit to one rate reduction
S192.5: unused
S192.6: unused
S192.7: Print SA/Adaptive answer debug messages
- S193 changed
S193.0: External COM device PnP enabled
S193.1: reserved
S193.2: reserved
S193.3: reserved
S193.4: reserved
S193.5: reserved
S193.6: reserved
S193.7: reserved
- I10 feature list modified and/or added 170, 174,176 and 177.
170=Handset support (record/playback messages through headset)
171=Headset support
174=VoiceView Support
176=Full-Duplex Speakerphone
177=Hands-Free Phone (use headset for hands-free phone)
- The sequence "ATM3", "ATDT;", "ATDT1234567" did not turn the
speaker off while dialing. (NOTE: Windows 95 dials by sending
a "ATDT;" followed by a "ATDT1234567". So the behavior with
"ATM3" set is not the same as older software which dialed
in a single command.)
- S191 (ARA EQM bias) was changed to 129
- TX level default (in -dBm) was changed from 12 to 10 in the US
country setup. This will cause some connections to connect one
data rate higher.
DISPLAY CHANGES
- S194 display controls (store in NVRAM via &W, but its setting is
not changed by the &Fn commands)
Setting both bit 0 and 1 bit active at the same time will result
in mixture of Reduced and Enhanced modes and is not suggested.
S194.0: Simple display mode - Reduced Display Data
S194.1: Debug display mode - Enhanced Display Data
S194.2: reserved
S194.3: Display rate change requests
S194.4: Demo mode (display shows canned messages)
S194.5: Display update times (0=fast, 1=slow)
S194.6: unused
S194.7: unused
SIMPLE Display Mode (S194.0=1) :
LCD models in FAX mode show only:
"Fax" on line 1 and "Connected" on line 2
DATA mode shows only carrier protocol type
DEBUG Display Mode (S194.1=1):
LCD models (SUP1330) show DTR, RTS and hook state
The messages are in are lower case when the signal
is off (or onhook) and in upper case when the signal
is on (or offhook).
EQM is indicated by:
(LED) "%Q" followed by "nn" where nn is the value
(LCD) "EQM:nn" where nn is the value
Received signal strength is indicated by:
(LED) "%L" followed by "nn" where nn is the value
(LCD) "RXL:-nn" where nn is the value
DTE rate is indicated by:
(LED) "DT" followed by the DTE rate code. Mixed
DTE rates (eg. 75/1200) and DTE rates
below 300bps are displayed as "03".
(LCD) "DTE:<rate>" in place of "(idle)". Only
rates above 600bps will be indicated.
Voice sample rate is only displayed on LCD (SUP1330)
units (when active)
- The TX and RX rates of a V.34 connection will only be shown
when an asymmetric connection is made. (Previous releases
displayed TX and RX rates if asymmetric rates were enabled
without checking if the remote modem also had them enabled.)
- #LCD=n,"string
This puts the string on line n of the LCD display.
All characters in the string are converted to upper
case for display. (This is a consequence of how the
AT parser works, all command lines are converted to
upper case upon entry.)
example: AT#LCD=2,"*Is Wonderful!* <CR>
AT#LCD=1,"The Sonic 288V+ <CR>
result: THE SONIC 288V+
*IS WONDERFUL!*
- #LCD=n,hexstring
This puts the ASCII characters represented by the hex
string on the LCD display. This allows the entry of
all 255 characters, including lower case, supported by
the LCD driver chip.
example: AT#LCD=1,54686520536F6E6963203238385628 <CR>
AT#LCD=2,2A497320576F6E64657266756C212A <CR>
result: The Sonic 288V+
*Is Wonderful!*
