Thanks for your detailed response, John.
I'll offer a bit more clarification.
When operating when installed on my old Thinkpad.... this DOS software

able to use the cable internet connection active on my Powerbook. In
contrast, my issue directly involves being able to use the Powerbook's
dial-up modem for a dial-up connection to a computer in a different
In light of the above clarification.... is there any further advice
that you could offer?
