I have set the speed with setserial and it shows this:

stty -F /dev/ttyS1

speed 19200 baud; line = 0;

min = 1; time = 3;

-brkint -icrnl -imaxbel

-opost

-isig -icanon -iexten -echo


Do I need to change one of the other settings?

Hello,

I had my lk204-25 working great with my laptop and linux using the LCD::MatrixOrbital perl module, although i had to hack it a bit to get it to compile on newer versions of perl:

Anyways, I moved the setup over a new computer, the permanent home ...
