Using a 10 or 4 Mhz xtal, doesn't means that you *WILL* get "occasional errors". And even less so if you are using any of the newer PICs with the 16 bit baudrate register (which I don't think that the target PIC in this case has). So, the fact that you are going to use RS232 comms, doesn't disqualify "standard" xtals altogether. > I worked for Procomm Plus in the late 80's, and it was > far better but driven out of business by Microsoft.
