Complete shot in the dark, but make sure you have appropriate permissions set on the /dev/ttyS0 files. That has bitten me in the past...

already thought of that, i even tried running the script as root. it seems to have no problem with me `print()`ing to the serial port, but reading in any data, it's as if the module doesnt even see the port is there. `# it seems to have no problem here print SERIAL $IM{'POL'}; # but HERE... read(SERIAL,$data,$BUFFER);` [download] __________ Build a man a fire, and he'll be warm for a day.
