Hi,
I don't have control over the code - it's
probably burned
into this variant of the MCS-51....
That's pretty much a given, the 8051 family came with internal ROM (the 8031
family were pretty much 8051s without the internal ROM).
....Even if I have the bps rate wrong, I should still
some
garbage flowing across serial interface.
I wouldn't make that assumption so quickly....perhaps you have to send some
sort of initialisation string to the unit before it'll send any output?
TTFN - Pete.
