unfortunately the schematic you have is a little bit harder to be modified (i forgot about this one, I was remembering me just the first one).
You should obtain the transistors+resistors group as in the schematic on the first page.
The good news is, for the attached version you can spare the cuts on PCB.
Btw, the emitter is the terminal with arrow.
Later edit: yes, pin 22 is RB1.
@all interested: attached is a (hopefully) functional version of hard-usart interface. If someone tests it and has comments, please share them.
PS I think I should start to give some version numbers to the firmwares.
