- It is my understanding that the stock ATT asy driver will only handle 2
- com ports. There are two solutions:
-
- 1) install fas, a PD asy driver replacement widely available ( I
- don't know where, though)
-
- 2) this option is funky. Basically install the asy driver twice
- in the kernel by copying and binary editing the Driver.o file so all
- asy's become as2's, and installing a new driver called as2. You also
- have to make an as2.h out of asy.h, and change the one or two local
- variables in the driver that do not have asy in them to any unused
- symbol name. Edit a new space.c and as2.h files to use the ports and
- interrupts you desire. I have done it on my machine and it works fine.
