I have a 286 box running uport 2.3.0 and I would like to know how to
modify the kernel to enable irq2 and irq5 for serial service. Under dos
I am able to use com3 and com4 for running a modem and a dumb terminal.
I need to know just what modifications need to be done to the kernel using
the linkkit. After the kernel has been modified I assume ttypatch has to
then be used to make the deices. Has anyone done this before? ANY help
would be very much appreciated.
Thanx in advance,
|Sly|.

I'm now using interrupts 10 and 15 for com3 and com4 (with a non standard asy driver). The AT bus has lots of free interrupts. -- Jon Zeeff zeeff@b-tech.ann-arbor.mi.us Ann Arbor, MI sharkey!b-tech!zeeff
