I am using a very old version of DR/DOS that is embedded in the ROM of a 
hand held device.  I am using the DOS I/O functions (int 21H 3fh & 40h) to 
do the serial I/O required to transfer files from the hand held to a 
server.  Everything works fine unless I lose DSR during a write 
operation.  In that case I am getting the infamous 'Abort/Retry/Fail' 
message rather than just getting a bad status code returned.  Does anyone 
know of anyway to suppress the error message?
