There are two problems with FAS and VP/ix. The first is that whenever there
are characters with framing or parity errors read in from the tty device
VP/ix may lock up. This is fixed in FAS 2.08 (to be released this month).

The second problem is that a level change of a modem status input line
tends to lock up VP/ix as well, at least until you send out a character
to the port. This restarts the stalled input character flow. This is
due to an error in VP/ix 1.01.01. I don't know whether this is fixed
in later releases.
