There is an FAQ for PPI modems.

• 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
