Re: Serial port Debug messages



It isn't necessarily so common that you would want debug output going to a
serial port that you would actually connect to something other than a
terminal emulator. So of course if opening the serial port changes the baud
rate... then the debug port will not work as desired.

The debug output uses OEMWriteDebugString, OEMWriteDebugByte and similar
functions.

Hi,
Which part of the O.S does send the debug messages to the host system
through serial port?
After i opened COM1 port through a small application(thogh close handle is
been specified), the debug messages stopped... I need to look into the
driver
code, but is that a common scenario that after COM1 port is opened by an
application and closed, after that debug messages wont be coming?
Regards,
Sankarraj
