Is it possible to make unidirectional serial port via 1 pin with PBP?

[CuriousOne]

Yeah, time to implement GPIB in PBP or FSK

Serin2 already has handshake implemented! Why not use it instead of trying to re-invent the wheel?

From the manual:

SERIN2 DataPin{\FlowPin},Mode,{ParityLabel,}{Timeout, Label,}[Item...]

Receive one or more Items on Pin in standard asynchronous format. SERIN2 is similar to the BS2 SERIN command. DataPin is automatically made an input. The optional FlowPin is automatically made an output. DataPin and FlowPin may be a constant, 0 - 15, or a variable that contains a number 0 - 15 (e.g. B0) or a pin name (e.g. PORTA.0).
The optional flow control pin, FlowPin, may be included to help keep data from overrunning the receiver. If it is used, FlowPin is automatically set to the enabled state to allow transmission of each character. This enabled state is determined by the polarity of the data specified by Mode.

Because the flow control feature of SERIN/OUT2 uses an aditional pin and CuriousOne specifically specified that there was only one I/O pin available.

[Ioannis]

You are right Henrik. I missed that. Well, it is not guaranteed then...

Ioannis

[CuriousOne]

What about OWIN/OWOUT ?

[Ioannis]

As other said too, no guarantee that receiver will hear the transmission.
