12F683 - how to set it to use external 4 MHz clock?

COOL! Glad you got it working!

I do use hyperterminal much so I do not know for sure the command but here is something from way back. Looks like it says almost the same as you are trying???

Hi,

Thanks for your email. I saw that webpage before but couldn't get it to work. However, the problem was just familiarity with picbasic/this whole setup! I simply looked up the ascii codes and send them as you would expect, and it 'does' work

serout Serial_out,T9600,[27,91,50,74]

I'm just putting some error checking into the routine, to try and make it at least a little fool proof. It just feels so good now that I have comm's with the PIC. Feel like I've got over a full hurdle. Reliable comm's back and forth is so important to allow one to develop this stuff!

I'll not add any further questions to this thread as I'm going off topic with my next issue. I'll see how it goes and then if desperation calls, I'll call you! I want to try to have 3 pic's all reading off the same RS232 RX line[and TXing on the same line]. Each PIC will be programmed separately with a unique identifier and will only address the TX line if it received data relevant to itself. But, I don't want to cover the board with 4 MHz xtals so I'm going to try to run 3 of them off the one xtal! Not sure how possible that is, but if it works, then great :P

Anyway,

Thanks to you and all for your help in getting me started on this PIC stuff. Feel like I've just been given my first car and have the freedom to go anywhere!
