- 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
