Heyu. That's funny.
I say that to my x10 stuff all the time, usually followed by "i'm talking to you...."
That's why the developer named it so, his kids moved out and he missed saying, "Hey you, turn off the light!"
I'm looking at buying a serial PCI card for $5-$10 off a guy, stay tuned. I'm sure to have a lot of questions once I get this thing running, especially if it's all glitchy like I expect.
Ordinary 1 or 2 port serial PCI cards are generally automatically recognized by Linux, although with some Linux releases the port numbering may be a little unexpected, e.g., with some kernel versions on my system the add-on ports are /dev/ttyS2 and /dev/ttyS3, whereas with other versions they were sometimes /dev/ttyS14 and /dev/ttyS15.
If your PC has USB ports, another option is a USB-Serial adapter. Heyu runs fine with these. For Linux, adapters with an FTDI chipset are generally preferable to those with a Prolific chipset. Byterunner (
