16 bit comm issue

Hi,

There's a problem with the current 16bit comm architecture which i'm
not sure how to solve correctly.

If a 16bit Windows programs uses EnableCommNotification to receive
WM_COMMNOTIFY messages then sits in a message loop waiting for them,
it will never receive them because there is no chance for APC that
sends the message (COMM16_ReadComplete) to run. 

I have a patch for this problem which puts an alertable wait in
GetMessage(16), which i posted in October.

What is the problem with this method, and is there a better solution
to the problem?

Mike
