I'd probably look into Bluetooth- or Zigbee-based serial
extenders.
Yes, I have, and still am, considerign those. Somebody else suggested the
Xee module, I had haeard of that. But do any of them work without any
flow control lines back to the host? The simple radio module (on the
433MHz band) that I looked at certainly eneded the RTS/CTS flow control
or something equivalent.
I'm fairly sure you could use something to fake the flow control lines.
My first thought would be to use some sort of microcontroller to buffer
a few bytes from the serial port, drop the link into tx, send them, and
go back to rx again.
This is basically what commercial 433/466MHz links do.
