[comp.os.minix] Minix-ST with rs232/midi

kyne@nadia.UUCP (Nicolai Matthiessen) (07/23/89)

I have still problems running the Minix-ST with rs232- and midi-add.
I've fixed the new kernel using the OCRMOD (that works fine), not share
procs with tty.c, not allow a normal TCSET to change to baud 0 ....

But when I write to the rs232 port after some bytes (dependent on the
size of the output) the output stops. In the variable tty_cum is the
correct number of bytes - but not on my connected terminal! The same
problem arises when I'm logged in via the rs232 port. When I'm logged
in via the rs232 port after the first (incomplete) output the mode flags
in sgttyb.sg_flags are changed (e.g. no ECHO) and cannot be set (e.g.
with stty) to other (correct) values. In login.c I set the correct
values, and no problem until I login and call the first program.
In login.c I set the baud rate with args.sg_ispeed=B1200 (sgtty.) and
I can login with the selected baud rate. But when I'm logged in the value
of args.sg_ispeed is always undefined!
Next problem: When I type on the console 'stty </dev/tty1' the rs232 port
gets stuck!

Are these known problems with a known bug fixes??? I do not have a new
login.c. I have compiled the kernel with the original ioctl-lib and
the ioctl-lib posted with cu.c - same problem. If there are fixes to
ioctl.c or login.c needed - please post or mail them!

Please, help me! After 2 weeks of 'fulltime-Minix' I don't know how to
go on with that problem!


Greetings Nic
