I don't have the 16F8XX datasheet on me. But from what I can see of the 18FXXX data sheet setting the SBRPG = 0 will give you the maximum baud rate. I'm not sure if the formula is the same for the 17F8XX, but for the 18FXXX you need to solve; Baud Rate = Fosc / [Y (X +1) ] Where Y is 64 for Aync lowspeed, 16 for Aync highspeed and 4 for sync low speed. For the 18FXXX it's 10000kb for Synchronous and 2500 kb for Async - tables P169 - P171 of DS39564B. Michael -- "Don't say yes until I finish talking." -- Darryl F.
