That sounds really cool. What did the game do?

I wanted to mention that I was messing around with OS/2 and the SIO drivers
recently and could not for the life of me get the door games to work in a
Telegard BBS. The connection was dropping as soon as the door loaded.

I discovered the fix in a document that you wrote probably 20+ years ago. It
was something as simple as placing an underscore at the end of the line that
setup the virtual port. I saw NOTHING in the docs about this! 

Anyway, I recognized your name on the file and wanted to say that it was
helpful even so many years after the fact!
