Changing Com Port Number
From the Device Manager, Select Properties, Settings, Advanced.
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, or the registry may need to be
edited with Reg. Edit or a similar utility.
After selecting a new com number, Click OK, then OK again on the
Settings page.
