ehouse d6163b62ff Add code, disabled in Makefile, to use rfcomm rather than l2cap for 
data with the goal of detecting disconnects more quickly.  Stops
working after a few packets (client only tested against host on linux
so far), and doesn't compile for ARM yet, but the framework is there.
Am framing packets on Palm side which may not be necessary.

use piconet? With that, HOST sets it up and clients join. That establishes
ACL links that can then be used to open sockets. I think. How to get from
piconet advertising to clients connecting?
See http://www.palmos.com/dev/support/docs/palmos/BTCompanion.html
NOTE: I've read conflicting reports on whether a listening socket is good for
accepting more than one inbound connection. Confirm. Or just do a piconet.
