[FONT=Tahoma][SIZE=1]The receiver is eanabled or disabled by bit 1 (RXDIS) in the RS485CTRL register (offset 50 hex).

If it is the [I]interrupt[/I] for received characters look at bit 0 (RBRIE) in the interurrupt enable register.
(IER, offset 04 hex).

It's all there in the user manual -- you just have to read it carefully.

Cheers, Mike
