flexfax: FIX for ACF II Rockwell 56k modems

[<avi@itsg.net.au>]

just thought i would share some minor success with the list.

modems that use the above chipset will not receive any faxes
with the default line in the config.ttyXX file:

ModemAnswerFaxBeginCmd: "<19200><xon>"

they will instead offer an "Unspecified Receive Phase B error (code 70)"
message in the log. the line comes in the file by default, so removing it
would be a good idea.


thanks,

Avi
