Jon:
You're being awfully helpful with this and I hate to keep prodding
you for more information...
But.
Your idea is intriguing and while I can see how to peek and poke
bytes with Liberty Basic -- I don't understand how to use the Basic
Stamp editor to peek and poke into my PC memory...

Your LB program will do this:
1) Read the file into memory
2) Loop through file data
-- send command to write, address, and data to BASIC Stamp
On the BASIC Stamp side, things would look like this:
SERIN Spin, Baud, [noparse][[/noparse]cmd, addrLo, addrHi, dByte]
IF (cmd = $C0) THEN
GOSUB Write_Byte_To_EE
ENDIF
IF (cmd = $C1) THEN
GOSUB Read_Byte_From_EE
SEROUT Spin, Baud, [noparse][[/noparse]cmd, addrLo, addrHi, dByte]
ENDIF
Hopefully this makes sense now -- the PC program is commanding the BASIC
Stamp. $C0 is the command to write a byte, $C1 is the command to read a
byte back. That way you could, for example, verify the contents of an
EEPROM with a file.

the data to EEPROM, it SHOULD send back some
kind of 'ACK' byte to LB.
LB should wait for the 'ACK' byte, wait a
little longer once it gets it, then send the
next message to the Stamp. This will let the
Stamp start up its SERIN before LB sends the
data.
