I use MSComm comtrol to write and then read from com port.
When I send string to Com port, hardvare connected to com returns data. In Win 95/98
that works just fine.
But on NT machine MSComm1_OnComm() procedure
doesn't execute so I get no response from hardware. Acctualy hardware do respond (I see it from the control inicators on it), but I can't read it.

Any suggesstions?
