  There is an FAQ for PPI modems.

CLASS 2 SUPPORT

- Defaulted subparameters in `AT+FDIS` and `AT+FDCC` commands are wrongly treated as zero
- `AT+FDIS` commands to set session parameters after establishing a connection with a remote machine are accepted but ignored; this makes it impossible to select/change data format (1D vs 2D encoding) and vertical resolution (98lpi vs 196lpi); to workaround the problem use the Class2DDISCmd configuration parameter
- RTC appended by the modem on page transmit appears to be invalid; the host should append a proper RTC
- EOM followed by a T2 timeout is handled incorrectly; the modem restarts Phase B of the protocol but then goes into an indeterminate state
- Page data reception is triggered by DC2, not DC1
- Fax receive is locked at 19200 and only software flow control appears to be supported
- It is not possible to disable software flow control during page data transmit
- HDLC frame tracing (`AT+FBUG=1`) is not supported
