Hi Todd,

In the future, if there ever does become a conflict with other equipment, with those low port numbers that apcc is
currently using, then what would the best practice be to assign higher number virtual ports that would be less likely to

APCC allocates virtual ports at runtime, not at system boot. Devices like a USB to Serial converters usually allocate their virtual COM port at system startup, well before APCC runs. APCC will also never use an existing (true) serial port as a virtual port.

When you run APCC, if it finds a virtual port in use that was previously configured for APCC to use, APCC will choose a different virtual port and reconfigure the driver to use that port. So there should not be a problem if you have all of your devices that use COM ports allocated before starting APCC.

Ray,
Thank you for that. Sorry for the delayed response as I was offline for a couple of days.

In the future, if there ever does become a conflict with other equipment, with those low port numbers that apcc is
currently using, then what would the best practice be to assign higher number virtual ports that would be less likely to
conflict? I guess that I’d like to know a path to follow if this happens, and it is on a perfect night at midnight, which is
when Murphy usually visits my observatory. It could save a wasted night. Only so many each year as you well
know...lol

thank you!

Todd
