Mildly off topic, PL-2303

Heyas everyone,
I recently liberated a usb to serial convertor based on the PL-2303 bridge controller. I am running gentoo linux, and I appear to have it installed and configured correctly; the drivers are built into the kernel and it seems to work. However, attempting to use a perl script I wrote that worked fine when it was on a normal serial port fails miserably when trying to use it with the convertor. I'm at a loss, has anyone managed to get a PL-2303 based convertor to work with a MO under linux? Thanks!

I did the same work as you did...
But I successed....

First, I got a prolific PL2303 official demo board, I use it with GLK12232-SM connected, running my own C program under Linux (RH7.1). I am sure the PL2303 driver and hardware were right(Connect LED ok, TX blinking) but GLK12232-SM just didn't work.

After that, I check the PL2303 output signal level. I found my board's output isn't EIA/TIA 232 compatible signal level.
So I attached another board to tune it and successed.

Maybe you should use a "MAX232" or something compatible to tune the signal into EIA/TIA 232 standard.
