Hello Keith,
I have seen similiar behaviour with windows on com ports. It seems as if
Windows is continously trying to identify new hardware which is attached. For
that purpose RTS and/or DTR are continously toggled hi/lo. Some modems react
to these signals with responses on CTS/DSR which (can) signal a presence of
such a device to the computer.
Try the following:
Start any software which uses the com port and see if the phenomenon goes
away. If so it's most likely Windows. If not something is seriously wrong.
If it's windows - good luck. I do not use Windows much more anymore so you
might go and check the Microsoft user support pages for a patch or a setting
which stops this behaviour.
73,
Ekki, DF4OR
