I have a problem connecting an old serial device (a weighing machine) in RedHat Enterprise Linux 4 ES.

I tested telnet from another computer with the same cable and the communication is correct when I use de default settings.

It seems I can’t use the correct options and commands to configure the serial port. I tried to use a line on inittab with “m:2345ff:/sbin/agetty 9600 ixon …. ttyS1”;
I tried to put the stty line on rc.local.

I think setserial command does not allow all the parameters I need…
I think there is another issue about controlling the flow between the devices and maybe another one with UART capability of devices.

On SCO Openserver I used to turn around the problem editing the S80lp file and introduce the following line:
(stty 9600 ixon ixoff –ixany parenb cs7 ; while :; do sleep 3600 ; done) </dev/tty2a &


Can please someone help me in this case?
