How to setup - USRobotics USB Model 5637 on linux

After having issues and googleing for several hours I thought I would post the correct configuration for this modem to work correctly in linux.

The errors I had before appling the code to config.ttyACM0; 

1. MODEM /dev/ttyACM0 appears to be wedged
2. ANSWER: Ring detected without successful handshake

Copy and paste below to config.ttyACM0

  3. Modem-related stuff: should reflect modem command interface
  4. and hardware connection/cabling (e.g. flow control).

ModemType: Class1 # use class 1 interface ModemRate: 19200 # rate for DCE-DTE communication ModemFlowControl: rtscts # software flow control

ModemSetupDTRCmd: ATS13=1&D3 # setup so DTR drop resets modem ModemSetupDCDCmd: AT&C1 # setup so DCD reflects carrier (or not) ModemNoFlowCmd: AT&H0 # setup modem for no flow control ModemHardFlowCmd: AT&H1 # setup modem for hardware flow control ModemSoftFlowCmd: AT&H2 # setup modem for software flow control ModemResultCodesCmd: ATQ0X4 # enable result codes

ModemMfrQueryCmd: !USR ModemModelQueryCmd: ATI3 ModemRevQueryCmd: ATI7 # XXX returns a multi-line result

  2. When AT+FCLASS=1 is issued the modem automatically switches
  3. to software flow control; these parameters let the fax software
  4. reset flow control as needed after entering Class 1.

Class1NFLOCmd: AT+FLO=0 # setup modem for no flow control Class1HFLOCmd: AT+FLO=2 # setup modem for hardware flow control Class1SFLOCmd: AT+FLO=1 # modem does this automatically

  2. This should resolve "DIS/DTC received 3 times" errors:

Class1ResponseWaitCmd: AT+FRS=1 # wait after sending TCF for response

  2. The remainder of this configuration is included so that the
  3. modem "idles" in Class 0 while not sending or receiving facsimile.

ModemSetupAACmd: AT+FCLASS=0 # leave modem idling in class 0

    1. ModemAnswerCmd: AT+FCLASS=1A # answer in Class 1
  3. When using AT+FRS=n we see USR modems reset themselves in the middle of sessions
  4. this is not good. So, we seem to work-around that problem by not using the
  5. command. Unfortunately, this isn't an ideal thing.

Class1SwitchingCmd: "<delay\0727>"
