[comp.sys.ibm.pc] COM1 port problem

wg@cbnewsm.ATT.COM (Bill Gieske) (08/15/89)

I have a Leading Edge Model D, with a built-in serial port (COM1:).  The port
was fine (I think) before I shut the system down for a week when I went on 
vacation.  When I powered the system up a week later, the port was bad - it
is sending continuously.  I observed this by monitoring the status of each
pin on the line.  As soon as the system is powered up, the line goes high - 
even before the system goes into bootup diagnostics.  Any suggestions on what
next to check, or what do do?  Thanks!
