It's my bug until I prove otherwise...unfortunately. Some
people say "don't use overlapped I/O when using serial
ports". Others (including Microsoft) say to use it. Who
knows. I'll get it fixed in time by the "puling out hair and
banging my fists on the table" method.

I've been doing serial I/O (in software) since before BASCOM, yet I've
never come across "overlapped I/O", as a term. Do you mean handling 2
ports simultaneously? What language? How are you doing the I/O?
(ocx? raw code?) (The program I'm currently working on does serial
and internet simultaneously, but that's not the same thing.)
