TO be succinct: beats the hell out of me!  Obvious questions:  do you
have the comm ports enabled as COM1, COM2 in the bios setup?  Did you
ever run 'full hardware detect' on boot? I'd ask if you had comm.sys
loaded, but since you see the addin board that would be insulting. 
My 503 works like a champ - external modem on com2 - with the only
differnce being the use of SIO.
