I'm looking for serial port drivers for the PC version of Xinu. I want
to use Xinu as the core of a multi-port communications program, but I
need drivers that will talk to the UARTs and the Interrupt controller.
Anyone know where I could find this?
Thanks!

There are no serial drivers that "come" with XINU. In fact, the book leaves it as an excercise. You might try CTASK, which I THINK has some serial routines. If you can't find it, I'll e-mail you a copy. So either that or write your own. In case somebody has written a set, could you forward me a copy?

The network version of PC-Xinu, which incorporates all the code and features of both Volume I and Volume II of Comer's "Operating System Design" books, includes an interrupt-driven device driver for SLIP (Serial Line IP) packets for point-to-point network connections. This driver can clearly be modified to serve as a low-level terminal driver as well.
