INF: Number of Serial Ports Under OS/2

ID Number: Q41255

5.10 6.00 6.00a

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.
