Hey, i think i got it.
 

This is what happens when you use code you didn't write and don't fully understand.

The line below in red is making the system expect 1.5 bit periods for the stop bit. (I think)

So since I was only setting vixen to 1 bit period for the stop bit, every once in a while the most significant bit would get incorrectly set to one.

Thus why I only get flashing and never quick dimming.

 

So i think if i change this from a #6 to a #4 it will work.

 

(But do i really care to take the time to test it when just setting the stop bit to 2 will work. Would up my max channel count to fix it.)

 

Does anyone agree this is probably the source of the problem?

 
bank #rx_count
movb c,/rx_pin      'serial receive
test rx_count
jnz :rxbit      'if not, :bit
mov w,#9      'in case start, ready 9
sc       'if start, set rx_count
mov rx_count,w
[color=red>mov][/color]:rxbit djnz rx_divide,rxdone    '8th time through?
mov rx_divide,#4'baud
dec rx_count      'last bit?

sz       'if not, save bit
rr rx_byte
snz       'if so, set flag
setb rx_flag
rxdone
