Serial data with flow control help

Happy Newyear!!

I have been trying to get serial comms with flow control to work
between two BS2E's.

I got the program from the manual to work, so then proceded to add
it to my own program, which didn't work.

so i went back to the manual example and tried to get it to work
again, and guess what, I couldn't get it to go!!

OK so in case I have blown something up, I have tested each stamps
I/O functions for the pins concerned. Each stamp can output a high
on each pin, and each stamp can detect a high on each pin. I then
tested the serial out to a LCD on each pin and it works just fine.

I simply can't work out what is going on. Can anyone suggest
anything else I should be looking at?

Regards,

Dwain.

    You need to post your code. Asking what's wrong with it without showing code
    is a lot like asking "My car won't run, whats wrong with it" at a cocktail
    party. Nothing to go on [noparse]:D[/noparse]

    You might find column #81 from "The Nuts & Volts of BASIC Stamps" useful.
    You can download it as a PDF from this link:

    I will look up the nuts and volts reference, thanks for that guys.

    After about 69 hours of frustration, I have finally found what was amiss.

    I was using a forward slash instead of a backslash in the pin definition
    part of the code, which rather than generating an error, simply stopped the
    flow control. Now there's a catch for young players!!

    Thanks again.

    Dwain.

    Don't you just hate it when that happens. Although, a lesson well learned.
    You will likely never make that mistake again!
