Hi all...

Welp.. Ive hooked the serial port interrupt...
Everything is going smoothly...
Yes, I'm going to lock everything down once i'm done doing some other things..
Anyhow.. my problem is this:

I miss characters which I should be receiving from the modem...
I set the serial port at 57600..  connect at 26400..  and receive only about
half to 3/4 of the characters that are sent to my modem..

I'm using V2 beta 2 (I assume beta 3 isn't THAT much different..)
Thus, in dpmi, all interrupts should be reflected to protected mode
and thus to my handler..  (I setup a realmode callback also but have
found that it never gets called)..   anyhow..  if dpmi reflects
everything back to protected mode..  why am I losing interrupts?

Any helpful hints?

Thanks,

Sam
