There is online documentation and an FAQ for Digicom modems.

• AT+FMFR?, AT+FMDL?, and AT+FREV? all return "3" in some versions of firmware (where vestiges of Class 2 support were present)
• ATS17=2 can be used to force 1300 Hz CNG tones to be sent (the register is not documented)
• RTS/CTS is not honored while sending page data; software flow control must be used (AT*F2). This is fixed in rev 3507/3506 firmware by adding a register S24 that can be used to control flow control in facsimile mode:

  0 means use XON/XOFF,

  1 means use RTS/CTS, and

  2 means use whatever is specified by AT*F.

  Note however that S24 is not permanent; it is reset after each disconnect. On power on S24 is 0. S24 is unchanged by AT&F.
• Receiving at 4800 baud v.27 does not work correctly; received data is garbage (fixed in firmware revision 3225/3310).
• Commands must not be sent to the modem too fast, no more than every 50ms (or more) depending on what the modem is doing.
• The modem gets confused by receivers that assert a data carrier before sending CED; a +FCERROR result is returned before usually returning "NO CARRIER"; this can sometimes be overcome by sending 1300 Hz CNG tones instead of the normal 1100 Hz tones.
