Yes, you will have to buy your own Max232 chip to convert some of the ttl level serial ports. You could put that externally. Or maybe you can interface to something that has ttl level serial ports. TS is working on a board with a zigbee socket and RS232 level converters, but I don't think they have released that, and in any case, it would not be compatible with the wi-fi daughter board. They would probably give you the schematics though, so you could duplicate the part you need. Of course the trick is then figuring out how to connect it . . . .

The problem is physical. You must unplug the WiFi connection in order to plug in the
development interface that has the RS-232 terminal connection. You can have either the
terminal or the WiFi connected, not both. Debian is set up to restrict telnet to root so to
access and change libraries the terminal needs to be connected.
