(X: indicate your CD-ROM drive.) 2.5 Cirrus 56K FlashROM When you download a new firmware for Cirrus 56K modem. Please follow the following procedure: 1. At DOS command prompt. 2. Find the file "FLASH.EXE" in your Video Excel CD title with the path "X:\MODEM\CIRRUS\MD5650\FLASH\". 3. Use the command "FLASH -C2 *.BIN" C2 : When your communication port is setting to COM2. *.BIN : The new firmware. 4. When the command is executed. The flash procedure is complete now. Section 3. Commands Most people use the communication software programs to tell modem what they want the modem to do.Therefore, you may not use the commands in this chapter. However, if you prefer to communicate with your modem more directly, you can type the following commands. Please note that when your typing appears on the screen, your modem is in a "terminal mode". this chapter will be helpful if you like to work in a terminal mode. 3.1 Note When Typing Commands þ Use the BACKSPACE key to delete typing errors. þ Every command (except A/ and +++) must begin with the AT or at prefix and be entered by pressing the ENTER key. For example, to execute the V command, you would type ATV and press the ENTER key. þ When you see an n, replace the n with one of the letter or numeric options listed for that command. For example, for the En command, you might type ATE1. þ If a command has numeric options and you don't include an number, zero is assumed. For example, if you type ATB to indicate a Bn command to be ATB0. þ All defaults are based on the &F Hardware Flow Control template load in NVRAM when the modem is shipped. 3.2 AT Commands A/ Re-executes the last issued command. Used mainly to redial. A Go off-hook and attempt to answer a call. AT? Read Selected S-Register. This command reads and displays the selected S-Register.

The +MS=m command specifies the allowable connection modulatios and data rates. The +MS=m command uses four parameters: <carrier>, <automode>, <min rate> and <max rate>. It is important to remember that the ordering of commands is important in configuring the modem. For example, if the DTE 9600 bps data rate and the AT commands are issued in the following sequence, different connection rates result: 1. ATS37=0 2. AT+MS= V32B, 1, 0, 14400 AT+MS=V32B, 1, 0, 14400 ATS37=0 ATDT1234 ATDT1234 CONNECT 14400 CONNECT 9600 3.3 Voice Command Summary IS-101 Voice AT Commands Reported Command Function Default Range by & Vn ========== ============================ ========= ========== =========== +FCLASS=8 Voice mode selection 0 0,1,8,80 yes +FLO=n Flow Control Select 1 0-2 no +VBT=m Buffer threshold setting 192,320 192,320 no +VCID=n Caller ID selection *0 0-2 no #VCSD=n Voice command mode silence 0 0,1 no detection +VDR=m Distinctive Ring selection 0,0 0-255,0-255 no +VEM=m Event reporting and masking 'C' BB860980 - no BFE63883 BB863EE0 +VGM=n Speakerphone microphone gain 128 121-131 no +VGR=n Receive gain selection 128 121-131 no +VGS=n Speakerphone speaker gain 128 121-131 no +VGT=n Volume selection 128 121-131 no +VIP Initialize parameter - - no +VIT=n DTE/DCE inactivity timer 0 0-255 no +VLS=n Relay/speaker control 0 0-16 no +VNH=n Automatic hang-up control 0 0-2 no +VRA=n Ringback-goes-away timer 50 0-50 no +VRN=n Ringback-never-appeared timer 10 0-255 no +VRX Record mode none - no +VSD=m Silence detection 128,50 no (quiet and silence) +VSM=m Compression method selection 140,8000, 0,0 no +VSP=n Speakerphone on/off control 0 0,1 no #VSPS=n Speakerphone type selection manufacturer 0,1 no -specified +VTD=n Beep tone duration timer 100 5-255 no +VTS=m DTMF and tone generation none no +VTX Play mode none - no * Noted parameters, commands, and responses depend on the capability to receive. 3.4 Result Codes Numeric Verbose ========= ========================= 0 OK 1 CONNECT 2 RING 3 NO CARRIER 4 ERROR 5 CONNECT 1200 6 NO DIAL TONE 7 BUSY 8 NO ANSWER 23 CONNECT 75/1200 22 CONNECT 1200/75 10 CONNECT 2400 11 CONNECT 4800 24 CONNECT 7200 12 CONNECT 9600 25 CONNECT 12000 13 CONNECT 14400 59 CONNECT 16800 14 CONNECT 19200 61 CONNECT 21600 62 CONNECT 24000 63 CONNECT 26400 64 CONNECT 28800 65 CONNECT 31200 33 CONNECT 33333 66 CONNECT 33600 34 CONNECT 37333 28 CONNECT 38400 35 CONNECT 41333 36 CONNECT 42666 37 CONNECT 44000 38 CONNECT 45333 39 CONNECT 46666 42 CONNECT 48000 43 CONNECT 49333 53 CONNECT 50666 54 CONNECT 52000 55 CONNECT 53333 56 CONNECT 54666 57 CONNECT 56000 58 CONNECT 57333 18 CONNECT 57600 31 CONNECT 115200 45 RINGBACK See Note CONNECT (DTE data rate)/ (modulation)/ (error correction)/ (data compression)/ TX:(DCE transmit data rata) / RX:(DCE receive data rate) NOTE: This verbose response code is used to evaluate the modem connection and is enabled by the W3 AT command.

When the modem is configured for text responses V1, the W3 verbose response codes provide information about the DTE data rate, connection modulation, error correction protocol, data compression, and modem-to- modem data rate. When the modem is configured for W3 and numeric responses V0, the modem responds as if it were set up for W0. 3.5 S-Register Definitions S0 No. of rings to auto-answer on Default: 0 Range: 0-255 Units: ring S1 Ring count Default: 0 Range: 0-255 Units: ring S2 Escape character Default: 43 Range: 0-127 Units: ASCII S3 Carriage return character Default: 13 Range: 0-127 Units: ASCII S4 Line feed character Default: 10 Range: 0-127 Units: ASCII S5 Backspace character Default: 8 Range: 0-32, 127 Units: ASCII S6 Wait before dialing Default: 2 Range: 2-255 Units: second S7 Wait for carrier Default: 60 Range: 1-255 Units: second S8 Pause time for dial modifier Default: 2 Range: 0-255 Units: second S9 Carrier recovery time Default: 6 Range: 1-255 Units: 0.1 second S10 Lost carrier hang up delay Default: 14 Range: 1-255 Units: 0.1 second S11 DTMF dialing speed Default: 70 Range: 50-255 Units: ms S12 Guard Time Default: 50 Range: 0-255 Units: (0.02 second) S14 Bit-mapped options Default: 170 Range: - Units: - S16 Modem test options Default: 0 Range: - Units: - S18 Modem test timer Default: 0 Range: 0-255 Units: second S21 Bit-mapped options Default: 48 Range: - Units: - S22 Bit-mapped options Default: 118 Range: - Units: - S23 Bit-mapped options Default: none Range: - Units: - S25 Detect DTR change Default: 5 Range: 0-255 Units: 0.01 second S27 Bit-mapped options Default: 64 Range: - Units: - S30 Disconnect inactivity timer Default: 0 Range: 0-255 Units: minute S31 Bit-mapped options Default: none Range: - Units: - S32 x2 mode enable Default: 32 Range: 0-255 Units: - S33 Sleep mode timer Default: 10 Range: 0-90 Units: second S37 Maximum line speed attempted Default: 0 Range: 0-35 Units: - Section 4. Appendix 4.1 Troubleshooting If you experience a problem with your fax/modem, refer to this appendix for suggestions on resolving the problem. 1. Why internal modem ( Without PnP ) can't install successfully in Win95 ? þ Please check "Control Panel"__"System"__"Device Manager"__"COM & LPT" item. Did the COM port for your modem's setting have been opened? If no! Goto the "Control Panel"__"Add New Hardware"__click "Next Step"__click "NO"__ click "Next Step"__then in "COM & LPT" icon, choice communication port, open the COM port for your modem. 2. If your modem doesn't respond to any AT commands. þ Make sure the modem is on. (externals only) þ Make sure you selected the correct COM port and IRQ in your communications software, and /or in your windows Control Panel. þ Make sure the computer is in Terminal mode of your communications software. þ Type in all upper (AT) or lower (at) case. þ There may be a COM port/IRQ conflict. Refer back to Internal Installation. You will need to remove your modem from the PC and change your COM port and IRQ setting to COM port 3 and IRQ 5 or 7. If you change your COM port and IRQ setting, also make the changes in your software and in Windows. 3. Type a command line and receive an ERROR result code. þ You typed an unacceptable command. þ Your command line contains more than 40 characters. 4. Do not receive a result code after your fax/modem executes a command line. þ All fax/modem result codes may have been disabled with the ATQ1 command. Send the ATQ0 command to enable result codes. 5. Your fax/modem responds to commands but your computer screen doesn't show the characters you type. þ Make sure the command echo is off (ATE1 in effect) to have your fax/modem echo commands. þ Make sure your communications program is configured to echo command characters. 6. Each character you type appears twice on your computer screen. þ Your computer or communications software has its echo feature is also turned on. If the system you are calling echoes your typed characters, turn off local echo at your computer, terminal, or computer software. If the system you are calling doesn't echo type characters, turn off the fax/modem's echo feature by typing ATE0 (which appears as AATT EE00 on your screen) and pressing the Enter key. 7.
