[Com0com-user] COM port addresses?

[Tom W. <tom...@gm...>]

Hello,

My MS-DOS program works fine talking to com0com on COM2.  But it
supports COM1-8.  I would like to run up to 8 copies of my program all
at once, each talking to a different com0com port.  But I tried to use
COM8, and my program doesn't see the port.  What addresses are COM5-8
on?

Thanks,

Tom
