- Wanted Help with resident device driver

I need a resident device driver that can handle an RS 232 port

- the MS-DOS driver for COM1: seems to be severely brain damaged

I want to replace it with a driver that has the following characteristics:

 - Buffers all incoming characters to the port
 - Buffers outgoing characters
 - support flow control XON/XOFF
 - The virtual device representing the port should be opened and closed
   as if it were a normal DOS file, reading from the device should extract
   single characters from the buffer or return end_of_file if the buffer is
   empty.

 - If such a driver (hopefully PD) exists please e-mail me

 - Failing this I'd appreciate tips on how to write such a driver using
   Turbo Pascal

 - Thanks in advance
