Dave,

See syncable.bas in the file section under Code 
Fragments/Mbasic for how to talk to registers and enable and 
disable interupts. At least as far as we have figured out yet. That 
particular segment uses timer W, but the serial port should be 
similar.

Important notes:

1. All Peeks and Pokes are offset by $F780. The memory map is 
inverted from the Motorola model with flash at the bottom and 
RAM at the top. Poke 0 actually pokes to $F780, the start of RAM. 
None of this is documented except in the forums.

2. All the registers are protected keywords and are used directly. 
That is LET SSR = %00000000 or LET TEMP = TDR works. 
According to Nathan, DO NOT use pokes or peeks and do not 
define the registers or register addresses (it's automagic).

3. The interupt commands are compiler directives, not keywords. 
For example, disable the interupt right before the interupt handler 
name label, not inside the interupt handler routine itself.

Via Con Dios,

Grant
