I am using a 16F690 which has an USART, cool, but all pins are used, not cool... I can use RA5 before the program uses it for communicating with another pic.

Using Hserout would be nice and adding an external osc too but I don't have the pins available for that.

Well, so I am confused.

The only pin I have is RA5, what should I do...
Use SEROUT, right?
And use a max232 (in this case what benefit to I have if the pic is already outputing RSR232 level signal?).
Whith what setting for SEROUT if not N9200?
And can I or can I not use an external OSC?
