I wouldn't be concerned if this was the first serial port that blew on my
Mac IIx, but unfortunately this is my forth blown serial port in two monthes
on a year old machine. I practice safe Mac: never unplug anything while the
machine is on. I've also checked for power surges and found no problems and
we connected my micom line to another Mac and it works great!

The message I get when using Versaterm:"Sorry the communications port is in
use by another program. You may continue off-line or try to use the
communications port anyway." This is in fact false, I'm not using another
program nor can I use the port anyway. MicroPhone has a more definitive error
message: "OS Error -28 occurred at point 500", which at least informs me that
the I/O driver is not open.

Has anyone else had similar problems with the serial port?
Our hardware support group is a little apprhensive to send the mother board
back for the forth time. Obviously they think the problem is me.

Thanks,
Dave
