TWO PIC's ON THE SERIAL PORT?...

/*_Dear Friends forgive the naivety of the question.
_I wonder if you can connect two controllers in a single MAX232??
_That is, the two controllers receive serial data, one sends the data back to serial port ...
_Here's an example for the connection in the following figure.
_Thanks to the atention and all information.*/

It seems OK, as both mcu receive the same message

It should be fine.

Is B1 the RX pin on both PICs and B2 the TX pin on the top PIC, if so your design should work. Is the softUART you are using of your design or some example code you found?

You can also work with a single crystal.
Connect the output of the first pic (pin 15) OSC2/CLKOUT (with crystal) to the input of the second pic OSC1/CLKIN (pin 16).

_But I not have code for this circuit ...
_Only one friend wants a board with two PICs and connectors for connection to the pins of the ports and nothing more ...
