2.2.2
Unable to connect direct serial or external serial modem
If you are using Windows
®
7 or Windows
®
8 make sure that you do not have more than
one modem driver installed to the same COM port. Typically this will only be necessary if
you use one COM port to talk direct (serial communications) and use the same COM port
to connect to an external modem. This is an apparent limitation in Microsoft’s
®
Dial-up
Networking. If more than one modem driver is installed for a particular COM port, Dialup
Networking will always use the last driver installed regardless of what is selected. The only
work around is to only install one modem driver per COM port on the PC at a time. Refer to
