flexfax: Wrongly informing a remote machine we have recieved a fax when we have not

[Chris Stenton <jacs@gnome.co.uk>]

I am using hylafax-v4.0pl1 on FreeBSD 2.2.6 with a Courier V everything
modem. I have just found out that I have not recieved some faxes that
remote machines were given confirmation of reciept by Hylafax. It
appears in all cases to be when the comms rate is negotiated down to
4800 baud. Here is a small section of one of the log files I have.

As can be seen it has not recieved any lines but sends back a message
confirm. Any idea what is wrong? Please e-mail me any reply. 

Thanks
