Problems with Asyncronous Communications

[BertMan]

Sorry, one more thing. I am using the internal 8mhz clock for testing purposes. Is this fast enough to keep up with the 19200 baud?

8MHz should work at this data-rate, but take into account that the iinternal osc can/will drift - so and it's not the best option for timing sensitve things like serial data exchange. A crystal is by far the best option if you want repeatable results under varying conditions.

Temperature changes will cause internal oscillator frequency drift & loss of communications/data. You have the option of tuning the internal osc to compensate for freq drift, but it's more of a pain than it's worth in my opinion.

Got it working! I decided to use a max232 and have been scratching my head as to why the pic still wasnt picking up the serial data from the micro 50. The resolution included taking a DEBUG statement out that was between the SEROUT and SERIN commands. I am hoping everyone has made this mistake before so I dont feel like a complete tard. Thanks for all the help.
