Lee, thanks for your answer.

Modem query AT+FDCC=? returns (0,1),(0-5),(0-2),(0-2),0,0,0,(0-7)
So, i think this parameter string must be appropriate for my modem (ACORP-M56EMSF):
Class2DCCQueryCmd:     "!(0,1),(0-5),(0-2),0,0,0,0,(0-7)"
i.e. only ln changed to A4.

I did some experimenting and have as result 3 types of behavior of fax machines:

1. Remote fax machine send unlimited page anyway.
2. Remote fax machine send 297mm of inserted page and report transmission error to the user.
3. Remote fax machine send 297mm of inserted page and hangs.

In all cases I had A4 page length negotiated on handshake.
I suppose that type 2 is absolutely correct behavior. But users don't mind that "transmission error" means unsupported page length! They simply repeat transmission again and again.

Regards,
Alexander
