(2) 33.6 compatibility with USR modem. Timing recovery routine is improved. (3) 32 state trellis coder compatibility problem. (4) Calling tone generation in V.34 mode is added. (5) 2100Hz tone detection is modified to meet French PTT requirement. (6) Dial tone detection filter is modified to meet European PTT requirement. (7) Non-Pentium driver connection/CPU speed is optimized. VPCTCOM.386: (1) Ring detection algorithm is enhanced to meet European PTT requirement. (2) V.23 Minitel connection fix. (3) &Y command handling. (4) Call progress tone detection for different country in voice record termination. (5) Handshake signal monitoring through sound card option. (6) Fix data/Fax mode switch in non voice auto answer mode. (7) Fix MCT inactivity timer test, speed adjust test problem. (8) Fixed calling tone generation in V.34 mode. (9) Fixed bug which causes unreliable blacklist function. MDMCHIPV.INF: (1) Resolve driver installation problem in OSR2. PTSERIAL.VXD: (1) OPD pin control is enabled. COMM.DRV: (1) IBM Internet connection problem in Win3.1. 07-26-96: Version 2.15 New features: 1) V.34bis/33.6kbps is added. 2) HSP speakerphone feature is enabled. This feature requires the full duplex audio driver support, such as: Crystal 4236/4232, ESS 1868/1888, Opti 931 and Creative Vibra 16. 3) International call progress tone handling (via %I command) are added. 4) Microsoft Visual C++4.2 are used for file generation. 5) V.34 rate renegotiation is added. Bug fixed: 1) Power management mode handling is modified. 2) Microsoft Phone voice playback volume issue fixed. Known problem: 1) ATD^ command does not generate calling tone in data mode. 06-22-96: Version 2.12 Hardware: 1). Resistor R101 is changed to 2k(was 27.4k)Ohm, Capacitor C53 is changed from 2200pf to 220pf on PCtel Revision D board Software: General: 1) Modem INF file modified, TAPI support added. 2) Microsoft APM2.1 support added. 3) Win95 installation sequence enhanced. PCMCIA/PNP/Non PNP are combined in one diskette. vmodem.386: 1). Added CPU utilization feature(default 70 %) 2). Improved v27 connectivity 3). Improved V32 connectivity 4). Improved V34 S/N 5). Added V34 pre-emphasis filter 6). Fixed V34 retrain problem with one of AT&T DSP based V34 modem 7) Improved system hang problem due to connection drop initiated from remote modem. 8) Retrain handling improvement. 9) Japan Link connection improvement. 10) Transmit level in all modes. vpctcom.386: 1) Auto mode connection to some low speed modem. 2) CNG detection in voice command mode. 3) S6,S8 timer modified. 4) ATD@ command. 5) Bug fixed for Q1 setting 6) &K5 (transparent XON/XOFF flow control) enables both local and remote XON/XOFF flow control, same as what Rockwell-based modems do. This "transparent" flow control is totally different from the original definition of transparent XON/XOFF flow control by Hayes. 7) For &S1 setting, DSP CD off caused by re-train won't lower UART DSR now. Data-DSP still has problems to keep its DSR_BIT consistent for both auto and fixed modes during the handshaking so you can see blinks on DSR light. 8) "TIES" escape sequence is corrected. *Qn command are added. 9) Transmit data stream in Direct Data Mode is regulated. 10). Default Transmit level is -11 dBm 11). 50ms fax Tx termination delay added to improve fax compatibility 12) Fix bug which causes sound level to change when pause function is selected in voice playback. 13) Enable class 1 mode switch in class 8 mode. vvoice.386: 1).Fixed busy tone detection 03-29-96: Version 2.11 Software: vmodem.386: connectivity improvement retraining improvement vpctcom.386: add commands for PTT test. report handset status in voice command mode. vvoice.386: fix the initial noise during voice playback. pctel.inf: HKR, Settings, ErrorControl_On,, "\N3" HKR, Settings, ErrorControl_Off,, "\N0" HKR, Settings, ErrorControl_Forced,, "\N4" HKR, Settings, Compression_On,, "%C3" HKR, Settings, Compression_Off,, "%C0" Removed those same lines from [NULL] section. 02-22-96: Version 2.10 Software: vpctcom.386: support AT\N as AT\N0 report RING BACK only when setting is ATX3 or ATX4 exclude 0x0a from the aborting character list PTSERIAL.VXD fix receive delay dbug. 02-15-96: Version 2.09B Software: vmodem.386: improved V34 S/N improved V34 receive level fixed CD drop problem fixed V34 handshaking compatibility problem with Multi-Tech V34 PCTEL.INF: Chg SpeakerVolume_Low setting from "L0" to "L1".
