[SOLVED] Library for half-duplex serial? (RX and TX from one pin)

[system]

Can you explain in more detail? You want to send only? Receive only? Hardware or software serial?

Both. I want bi-directional half-duplex. I need to be able to read serial data, set the pin to output mode, send serial data, and put the pin back into input mode.

I would prefer a hardware solution, but software serial should be OK as well.
