RE: flexfax: How to handle PIP

[Erik.OSTHOLS@oecd.org]

OK, thanks for the information. Seems probable that the fax at the other end
is indeed broken. Question remains why our fax machine can send to it but
not HylaFAX in its standard version. Regarding the flow control problem, I
tried using XON/XOFF for flow control (and setting speed to 9600), which
gets rid of the flow control problem you indicated below for outgoing faxes,
but then communication with fax machines calling in does not work well
(connection hangs). For the moment I will stick with the below, which, as
you noticed, indicates some kind of problem, but at least works both ways.
The communication is now set to speed 38400 and hardware handshake, which
was set by the installation procedure and which I gather from the docs
should work for a MultiTech MT2834ZDX.
