mask = 0x00000001 is EV_RXCHAR. The application wants to know if a new
character has arrived

But there is no new character . But it seems 0x216 characters have already
been received and 257 chars transmitted.

    Dan> trace:comm:Comm_CheckEvents OUTQUEUE 0, Transmitter not empty

This results from a wrong place Warn on about line 1810 in kernel32/comm.c
The warn should be place inside the braces of
if (mask & EV_TXEMPTY) {}
above, when the application ask for it when the mask bit is set.

Let me wait until Eric's recent changes regarding moving the COMM IOCTLs to
ntdll have been applied. I will then fix the error. It seems unrelated to
your problem, or at least not the cause.

Perhaps you can add my patch

to see if any real communication happens and see what is sent
