I got my OS2 com port problem solved.  Com ports on OS2 are easy but the 
documentation is misleading. No surprise here. Take a look at the manual and 
then ask for help interpreting it!

Thought someone else might have a similar problem sometime.  Here goes:

I have COM1 on Interrupt 5 with an internal modem, and COM3 on Interrupt4 with 
an external modem.  In Windows its a port setting in the Control Panel and 
all you have to do is fill in the blanks in the dialog box.  When I moved to 
Win-OS2 I found you have to manually change the Config.sys file.  I 
couldn't get it to work.  Then it worked...Here is the line that worked.

I changed the default:

DEVICE=C:\OS2\COM.SYS

to

DEVICE=C:\OS2\COM.SYS (1,O3F8,5) (3,03E8,4)

Now I can have two communication sessions going at the same time on two modems,
