Tracy,

No, I have a 1994 vintage spread spectrum modem by Proxim that supports
9600 baud coms. My first question related to getting the system to work
is to find out what data rate is used when downloading code to the BS2P
Stamp. If it can't be set to 9600 or less, I'm out of luck. If it can,
then I need to know what other settings are required (i.e. flow control,
etc.) Any ideas?

Chris

    The modem has to be "full duplex". Half duplex doesn't work, I know I have
    tried.
