basics of of bs2>bs2 serial communication

hi everybody.

I'm trying to set up a super-basic serial communication between two bs2.

I've connected pin 11 of the first stamp to pin 11 of the second stamp

the first stamp is running to following code >

here:
serout 11\11,16468,[noparse][[/noparse]65]
pause 100
goto here


the second stamp is running to following code >

my_var var byte

here:
serin 11\11,16468,[noparse][[/noparse]my_var]
debug my_var,cr
pause 100
goto here

I'm not getting any output in the debug window from my second stamp (which
is connected tot he pc via the serial cable)

I'm sure I'm doing something foolishly wrong, but I can't figure it out.
Any hints??

thanks!

    You need to connect the ground pins of the two stamps as well. And
    don't use the \Fpin option in either code. That is for synchronous comm
    only. Change your serout to serout 11,16468,... and the serin likewise.
