Jesus,

Option 1:
On the PIC, look for a setting called "idle state for transmit".  Change it to low.
As long as it is high the Rabbit serial port thinks it is getting a start bit

Option 2:
On the rabbit you MIGHT be able to set the receiver to look for a rising edge instead of a level.

Subject: [rabbit-semi] Uart from Pic to Rabbit



Hi,
                I'm trying to send some bytes from a Microchip Pic to a Rabbit2000 via UART with TTL levels. What I get in Rabbit is that bytes but also continuously I get the 0xFF byte. The TTL level from PIC's TX pin is OK (5V in idle time), what's wrong? Any hint?

Thanks!
Jesus
