Another thing that could be causing problems is that SEROUT2/SERIN2 are software bit-banged (no hdw UART involved),
so device B must be sitting waiting at the SERIN2 for the first start bit before...
Are these PICs on the same PCB or on each end of a long cable?
Cable (well PCB traces too of course) has capacitance, with a 10k resistor you're forming quite an RC-filter (relatively speaking)...
Yes it could be a problem. Try with no resistor and see if the problem is in your code or just the lack of power on the link. Then try max 1K resistor.
Hi, I have two devices communicating with SERIN2/SEROUT2. Device A, a PIC18F4550, sends data to device B a PIC16F19197. I'm receiving the data at device B using SERIN2, but like 1 out of 5 times I...
this can not work as you set the qualifier to 0x0d as per my example , ProgIDRx will always be 0x0d
untill you change it , serin will never change it

It's almost Olympics time... so here's a topical program using PBP exclusively (no embedded Assembler) to give you a Stop-Watch with 1/100th Second Timing (yes that's 0.01 of a Second) and gives you REAL-TIME display on your LCD. Now you can do your own timing and challenge the official time...
The program demonstrates using TMR1 in BACKGROUND (multi-tasking), uses PICBasic Interrupts, and accounts for the fact that PICBasic doesn't respond to those Interrupts immediately. There's also a set-Up CALIBRATION menu item, so you can adjust and calibrate your timer to an accuracy of 360mS per Hour.
How does it do all that? Better download the PDF and find out...
