Hello Vitus,

I hope you get my reply, because I don't seem to receive any replies to my 
messages in any of the international OS/2 areas lately. :-(

Has the driver or another process exclusively opened the serial port at the 
time your code tries to get access to the serial port, or does your code 
exclusively (try to) open the serial port?

Is the developer of the serial driver capable to realise the possibility he 
made a mistake in his code?
