We just recently installed a P4200 with 2 ethernet and 1 COM4 cards.  I
have been having problems with the COM4.  The box will come up and run
for a while then interface 0 goes down.  Testing the interface does not
help the problem.  We see constant receive on our DSU/CSU (a 56KB line)
but transmit is off solid.  Unplugging the ribbon cable from the COM4
and plugging it back in while the box is running corrects the problem
for a while but it goes down again eventually.  It will sometimes run
for 2-3 days before failing other times it will fail after only a few
minutes.  Proteon has sent a replacement COM4 which did not solve the
problem.  We are running an 8.0 software load.  Has anyone else seen
this problem and/or know of a solution?
