Hi!
I'm developing an app that communicates with the KS20 temperature
controller from PMA. This is done via an RS232<->rs485
converter attached to a serial port of a pc. On a 486 with 16450 the prog
works fine, but on a P133 with 16550A I only
receive 'garbage' (or encoded stuff?), while output is o.k. Manually set
the ttyS to 16450 or 8250 doesn't change anything.
I've tried different c_iflags without success.
Here's some bytes of output as it should be and as it is (in hex):
should be:
|command:set temp |-/+ temp 3.1 | cs | end
3A 30 31 36 36 32 36 30 31 30 34 2E 30 41 38 0D 0A
is:
8A B2 B2 92 B2 82 8A 82 A2 72 82 0D 0A
s.b.: 3A 30 31 36 36 32 36 2D 39 39 39 2E 39 38 43 0D 0A
is: 8A B2 B2 92 B2 6A CA CA CA 72 CA C2 0A
Any hints?
tia,
Michael
