How do you add ports to OS/2

How do I add OS/2 ports, like LPT4, LPT5 etc.. to OS/2.  It's so easy to do it in windows, all you do is edit the WIN.INI file.  Is it as simple as editing the OS2.INI file?  And if so how do I edit it?

OS/2 doesn't natively support more than 3
printer ports, as far as I know. Adding
COM ports is easy, using the syntax

DEVICE=COM.SYS (Port,Address,Irq Num)

in Config.sys and repeating the brackets
for each additional port you wish to

Printer ports are different. There *is* a
solution, however. Faxworks Pro for OS/2
allows up to LPT9 to be used for its fax
driver and there is a utility available
for download on the Keller Group's web
site ( which
adds the capability to OS/2 to support
printer ports LPT4 through to LPT9.

It might work for your application.
