Serial Port Settings was created by racedirector
I just loaded up a new PC to run my machine but this one is having trouble loading modbus via serial. I think it has to do with the port speed which for the life of me cannot get to stick. I installed the machine via the latest Debian iso.
setserial /dev/ttyS0 -a reports the speed at 115200 and I have been trying to get it to either 9600 or 19200 but it just doesn't want to, even setting stty -F /dev/ttyS0 19200 in rc.local. Being a Windows/Mac user I have only been trying this via google.
Am I doing things right or is there another/better way of setting the port permanently to 19200/9600?
Cheers
Bruce

Hi
I think the line you want in rc.local is something like
stty -F /dev/ttyS1 19200 raw -echo
Otherwise try setserial to make persistent changes
packages.debian.org/wheezy/setserial
