2. To View Serial Ports Under Device
Manager
- Look for the Ports (COM & LPT)
category and expand it. If the Ports (COM & LPT) category does not
exist, then your computer is not equipped with a Serial Port.
- Look for the entry which contains a
COMX designation (X is the Serial Port number). Ignore any
LPT entries.
- Note the Com Port number for later use
in MicroBase Professional.
- If no Com Port entries are displayed,
your computer does not have a working RS-232 Serial Port and you will have
to add one, or use another computer.

3. To Determine If Your USB to RS-232
Adapter Driver Is Installed Properly
- If you have installed a USB to RS-232
Adapter Driver, look for the corresponding Com Port entry and note the
virtual Com Port number which the adapter is assigned to use.
- If a new Com Port entry does
not appear under Ports (COM & LPT) when your USB to RS-232 adapter is plugged into a working USB
port, you probably don't have the appropriate driver installed. Try
installing the driver again.
- If you are not sure which Com Port entry
corresponds to your USB to RS-232 adapter, disconnect the adapter
from your USB port and the related Com Port entry will disappear from
the list. Reconnect the adapter and the related entry will re-appear.
- MicroBase Pro only supports Com Port numbers in the range
of 1-9. If you see a number outside of this range, try opening the
properties of the driver and then using the advanced configuration to
obtain an unused Com Port number in the range of 1-9. If Com Ports
1-9 are all used by other devices (rare), then you will need to
uninstall one or more of the drivers which are using Com Ports 1-9.
