The other pins can easily be toggled in VBasic, and TXD can't. That makes sense. I’m guessing it pulls current from the TXD pin, given this pin goes into the voltage regulator.

That seems odd. I'd think it would be connected to RTS and TXD pins. Is it correct that the Clock and Data lines are connected to the RTS (pin 7) and DTA (pin 4) pins of the RS232 cable?
