[Coco] DriveWire type OS-9 SCR driver?

[Allen Huffman]

Is anyone here familiar with how DriveWire for OS-9 works, with its serial I/O? Before I spend time trying to do something, I thought I’d ask to see if it was even practical or possible.

All I want is an SCR type driver that can send data then immediately read a response. Payload size could be specified by a setstat or similar.

setstat(path, XXXXX, YY); ...response bytes to read.
 write(path, "DATA", 4); ...send data out.
 read(path, buffer, YY);

I want to talk to a serial devices I am building, and while using T1 at 300 baud works, it would be nice to go faster and not need all the extra overhead of that driver for things I’d never need for my devices.

Thanks for your thoughts...
