port labeled ATEN USB to Serial Bridge (com#). Look for something similar
to USB Serial Port (com#) if using a different USB to Serial Adapter cable.

of cable from computer. Port should disappear from Ports list and then
reappear. If none of ports disappear and reappear with above test, computer
does not recognize USB to Serial Adapter. Reinstall drivers provided with
adapter and then try this procedure again. See Adapter Installation on page 9.

Removing USB to Serial Adapter Drivers
To reinstall the drivers or to change to a different device, it may be possible to
remove the installed drivers via a software process. Refer to the manufacturer’s
instructions for details.
CAUTION: If ports 1 through 4 are labeled “in use”, all ports may be
assigned to a connected device OR to software for a device
(reserved for use when device is connected). Although it may be
possible to successfully connect via a port marked “in use”, this
might cause a device or software program to malfunction – proceed
at your own risk! Sun Nuclear is not responsible for any damage to
your computer as a result of selecting a com port labeled “in use”.
