The simulated serial interface was optimized for the "single GPIO half-duplex" use case. As a two wire interface it works well for interactive use case since there is a delay between keystrokes.
When used with programs with line buffer and no delay between characters (like e4thcom) an implementation is needed that uses independent receive and transmit states.

Full duplex operation now works with "zero delay" between received characters (tested with W1209 and e4thcom). The serial interface simulation code was moved to include files.
