OS/2
Summary:
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.
