Available names for Com numbers are shown. Select a new number
from those not “in use”. Com numbers from Com1 to Com256 may
be available. Com numbers “in use” may be used by motherboard
ports, Modems, virtual com ports for network serial server devices or
FAX modem. Formerly installed USB to serial adaptors, PCI cards or
other hardware may have reserved a com number. The device may
need to be added back to the system, then the software removed.
Advanced editing of the registry may needed to clean up the
problem. Special permissions are required with 2000 or XP.
