With further investigation I have found that a hardflow_cmnd command, just
'AT' in this case, is returning VCON and not OK. Allowing this as an
acceptable responce seems to fix the problem. Is this too much of a hack
to include as a patch. Is there a case where you wouldn't want this to be
the responce?

The problematic modem is a US Robotics 56K voice faxmodem model number
5663, UK edition, which I think they have just stopped making.
