flexfax: Faxpolling gives REMOTE HANGUP: Unspecified Phase C error

["H. Gehrke-Tschudi" <hgt@vitzlipu.ruhr.de>]

I have HylaFAX (tm) Version 4.0pl2 with Linux-Kernel 2.0.35
(gcc version 2.7.2.1) Class2-Modem CREATIX SG 2834 running on a standalone
system.

Faxsending works ok.

When I try polling a fax I get:
`Unspecified Phase C error, including too much delay between TCF and +FDR
command`.

In my logfile Handshake looks OK. Only when it comes to actually sending the 
page from remote I get a MODEM TIMEOUT.

This is what Facsimile Agent takes to protocoll:

 'Unspecified Phase C error, including too much delay between TCF and +FDR
+command; too many attempts to send
