There's a certain breed of PIC microcontroller programmer that relies on 12v signals
on RS232 to provide enough voltage to trigger the programming. The USB to serial chips
I've seen so far are all 5v, thus they can't power such programmers.

Actually, adapters that use the FTDI FT232 are true serial ports (with hardware flow
control) and those work very very well. Drivers are also not an issue. We just had a

I do a lot. They don't always handle flow control or hardware null modem setups
right. Drivers are hit and miss and never updated. If you can even find the drivers.
