This is where my WISH LIST for software developers comes in.

I would like to have a serial port connection run the relays. many
relays are for things that do not have any timing issues, coolant
pump, vacuume, clamps... etc... Having use of relays on the serial
output would offer some neat possibilities.

Maybe for that EMC port......

There is 12 volts inside the PC, so that is not an issue.
