A mouse or similar device may not work correctly on buffered ports, such as those
offered with the PCI-FAST / AT-FAST cards. If possible, connect your mouse to one
of the existing PC serial ports. To configure the cards for connection to a mouse,
disable the buffering option as follows:

1. Run the atfconfig utility:

/etc/comf/atfconfig

2. At the Action? prompt, select M. Add a mouse port. A list of available ports is

shown and a prompt follows for the name of the port you wish to unbuffer.

Example: Type comf2c to unbuffer the third port on the second card.

3. Repeat as required for other ports.

4. Quit the utility.

An extra device will now be added to the /dev directory for each unbuffered port
configured. In the example above it is called com2c and this name should be
specified to the mouse software, etc.
