Hello,
There seems to be a few problems with serial support in elks:
- when elks is booted the speed of the serial port is set by bios (and on
my machine these speeds look random) - the patch sets it to 9600 baud
- sometimes ELKS hangs (falls into a loop) during boot after detecting the
serial ports (could be a problem with my machine)
- sometimes ELKS falls into a loop in rs_open when a serial port is opened
(also could be a problem with my machine)
I have written a patch for elks 0.0.74-pre1, which attempts to correct
these problems. It's a bit buggy at the moment, the first time the port is
opened after boot it doesn't work. One must start the comms program, exit
it and start it again.
i've made it avaliable at http://acid.ch.pw.edu.pl/~sq5bpf/elks
Also a small (working) serial terminal program is included.
Don't look at the code too closely - it's 4:00 am ;)
