I have problems with a machine running SCO Unix System V/386 R3.2v2 (just
upgraded from R3.2v0).  The machine is equiped with a Arnet Smartport 8
board and driver release 05.01.13.  Problems are associated with a Wyse 120
terminal with attached HP LaserJet IIP printer (uses the parallell port on
the Wyse terminal) and simultaiously using the terminal line for printing and
terminal presentation.
The problems arrises when users do logout during a prinjob.  
The terminal device line hangs.  This makes
further use of the terminal impossible.  The problem does not seem to be
with the terminal (turning the power off-on makes no difference).  stty
on the port that hanged is not possible (can't read it as root)
and the only cure I found is to reboot the machine.

This behaviour was not present using the same Arnet driver with SCO Unix
System V/386 R3.2v0.

Does anyone have a solution to the problem?
