A friend of mine is having REAL trouble writing a TSR that reads a serial
port (at interrupt time) and stores chars in memory until a NL is read,
when it dumps the line to a file. The data rate is 300 baud max and
max 80 char lines are received no more than once every 3 mins.

He is desperate but I know nothing about serious DOS programming!!
The application he is writing is non-commercial, he will make no
money from it (nor will anyone else).

Has anyone out there got a snippet of program that he can "borrow".

(he wants to run this TSR so as not to affect "normal" DOS functions
like word processing etc).

TIA (much)
