I have been setting up a MAX232CPE to try to get

serial diagnostic port. Trouble is I am not sure which signal is the
data signal. The one that is marked SROMCDAT in the technical manual
does not appear to do anything when I look at it with the scope. Anyone
know which is the right signal to monitor?
That pin is the Rx side or data input, so obviously you won't see
anything interesting there. The Tx side or data output is on BSROMCLK.
I'll send you a document page with conceptual schematics of the host side
of the circuit; off the list as attachments are not allowed here I believe
no matter how small.
