REF: Multiple HandyBoard with PC communication
Wireless
Greetings,
I would like to inquire about wireless communication among
HandyBoards and a PC. We are using a wireless modem with TCP/IP
capability (the Nomadic Mercury modem) and am curious to know
if/how anyone has tackled a problem similar to this before,

room for control programs.
Thanks for your attention and any info you may provide.

| Just another idea. What if you attached all the boards in a ring, sort of the token ring network idea that IBM used in their networks. Only make communications go in a clockwise path, and give each board an id#. Send the number and then the info. (...) (27 years ago, 17-Jun-97, to lugnet.robotics.handyboard)
