Hi Nate

I don't think that's the case any more. I think in release 1451 the FULL_RPC
is enabled by default.
For example, I have been unable to find the any approximation of the file in the following line

 (Gumstix): To effect the above change, set UCLIBC_HAS_FULL_RPC=y in gumstix-buildroot/uClibc.config.

and in gumstix-buildroot/toolchain_build_arm_nofpu/uClibc/.config I have 

UCLIBC_HAS_RPC=y
UCLIBC_HAS_FULL_RPC=y
UCLIBC_HAS_REENTRANT_RPC=y

which is how it came "out of the box".

Also on  the gumstix I see

# ./player roomba.cfg

Opening connection to Roomba on /dev/ttyS2...Done.
Listening on ports: 6665

closing connection to client 0 on port 6665
accepted client 0 on port 6665, fd 9
closing connection to client 0 on port 6665

The two sets of messages are as I  tried ./intro client.xml twice

So the gumstix is getting messages from my desktop computer but it seems like the desktop is not getting the responses. 

I had to do a ssh root@162.168.1.102 to get key loaded in some table so my host could
understand the gumstix encryption. Do I have to do a similar thing on the other side?

For more details on my setup you should see the message I placed in the Help Discussion Forum.
