8.1: HyperTerminal Closes the Port Unexpectedly


[Contributed by Taed Nelson (nelson@lan.nsc.com).]

A few people have run into the problem where, under Windows 95, HyperTerminal
will seem to load the port driver correctly, but then suddenly close it for no
apparent reason.

The cause of this is that HyperTerminal or UNIMODEM (it is not clear which is
the actual culprit) requires at least two of the four new W95 functions. See
below for more details. The functions it needs to use are PortGetCommConfig
and PortSetCommConfig.
