The number of serial ports that can be supported under OS/2 is
dependent on how your OS/2 vendor set up the device drivers
shipped with the operating system. Most are set up with two ports for
AT-type machines and three for PS/2 type machines. Each vendor writes
its own communications device drivers, so it really depends on what
the vendor is doing.

Note: Both original and third-party vendors can support additional
ports (essentially, as many as they like) if they write or modify
device drivers to do so.
