- For a complete listing of the AT commands for Supra modems see
- ftp://ftp.supra.com/pub/gen_info/at_list.txt
-
- Modem setup string for SupraFaxModem 14.4 & 28.8.
-
- The set up string for the modem configures its communications mode.
- Always be sure to double check all commands in the modem's manual as the
- AT command set is an informal standard. Even though they are the same
- model, different version may react differently to the same command.
-
- &F2 Restore factory defaults for
- use with IBM-PC/compatible.
-
- &S1 DSR follows EIA specification.
- Required for hardware handshaking.
-
- &C1 DCD follows carrier state.
- Required for hardware handshaking.
-
- W1 Result codes reported. Reports error
- correction being used, DTE, and DCE data rates.
- Helps in trouble shooting connection problems.
- For 14.4
- CONNECT 38400
- PROTOCOL LAPM
- CARRIER 14400
-
- For 28.8
- CONNECT 57600
- PROTOCOL LAPM
- CARRIER 28800
-
- S11=n DTMF Tone Duration/Spacing
- (35 to 102 1/100 seconds) (Default is 95)
- Set spacing and duration of touch tone
- tones in 0.1 second increments. Values of
- n<60 may cause dialing errors on some phone
- systems. You would use this to decrease the
- amount of time it takes to dial the phone.
- Its nice when you have to redial a lot.
- n = 70 (0.70 second delay between tones)
-
- Nn AutoMode Selection. Carrier Rate when
- Originating Call.
- n = 0 (Connect ONLY at rate set in S37 register)
- n = 1 (Connect at highest rate supported by
- both modems. [default])
-
- S37=n Forced Single Carrier Rate. Forces modem
- to connect at a specific speed and not
- negotiate a higher one. This is needed on
- machines that don't have 16550AFN UART's so
- that the serial port doesn't over run the
- processor under Windows.
- n = 6 (2400bps)
- n = 9 (9600bps)
-
- Example: SupraFaxModem 28.8 on a PC with a 16550
- UART running at maximum data rate.
-
- AT&F2&S1&C1W1S11=70
-
- Example: SupraFaxModem 28.8 on a PC without a 16550
- UART running at 9600bps so data doesn't
- overrun the PC.
-
- AT&F2&S1&C1W1S11=70N0S37=9
-
- Example: SupraFaxModem 28.8 on a PC without a 16550
- UART running at 2400bps so data doesn't
- overrun the PC.
-
- AT&F2&S1&C1W1S11=70N0S37=6
-
-
- Dialing strings are also part of the AT command set but are generally
- used in a different part of the communications program. Their purpose is
- to control the dialing process rather than the communications mode of
- the modem. Always be sure to double check all commands in the modems
- manual as the AT command set is an informal standard.
-
- D Dial the phone.
-
- T Dial using touch tone.
-
- P Dial using pulse.
-
- W Wait for dial tone before processing next
- character in the dial string. This is very
- useful when you have to dial 8 or 9 to get
- an outside line.
-
- @ Wait for 5 seconds of silence before continuing.
-
- , Pause before dialing next character in dial string.
-
- *70 In some areas this it is *71. Disable call waiting.
- This is required for reliable communications. If
- you have call waiting and don't disable it the
- communications could be garbled and/or the modem
- will just hangup when you get an incoming call.
-
- - This does nothing. It can be used in the phone
- number to make it more readable for the user.
-
-
- Example: Dial outside line on a PBX 555-5555.
-
- ATDT9,555-555
- or
- ATDT9W555-555
- or
- ATDT8,555-555
- or
- ATDT8W555-555
-
-
- Example: Dialing 555-5555 and disabling call waiting.
-
- ATDT*70,555-5555
- or
- ATDT*70W555-5555
