G,day again,

Thanks to all who gave tips on tapping the crystal oscillator. Tomorrow
I shall eat the pudding!


Now can anyone help set me straight (if that's possible) on the
situation with the built-in UARTS on the PICs. Yes I know there
has been a lot of discussion about them but I didn't take any
notice until I need to know.

I want a 15.2K baud link. Failing this, 57600 or even 38.4K baud.
For this application a software UART is out of the question,
(Though it can be achieved, it is just not suitable.)

Questions:

1) Can the UART in the PIC16C64/65/74 WORK CORRECTLY at these high baud
   rates? This would require BRGH =1 and isn't this supposed to be bugged?
   Do any of the devices work as stated? Are there work-arounds?

2) I might even use the 17C4x family. Does anyone know what OBTAINABLE
   crystal Frequency I should use for 38.4K, 57.6K or 115.2K Baud. All the
   high baud rates with the usual crystals are really odd-ball. I want to
   interface it with a PC at standard baud rates.

Can any superior intellect enlighten me?

Thank-you and Regards,

Jim
