That is interesting. I have rev C but no connectivity between pin 11
and pin 15. I've jumped the two together now.

Changing the baud rate in microcom to 115200 improved things a lot! I
thought I did not have to set it because I used the "stty" command to
set the baud rate in a startup script. Now I get the following output:

>Z
!

So it is echoing back characters (and a little more) but I am not
getting info from the modules in the chain. I went back and tried the
usb2serial and verified it still works.

Yes. Please send it to me.

Yes. I have done this test. Actually this test fails on /dev/tts/0.
I've been using /dev/tts/1which passes this echo test.

I'd love to but I am working in Redwood city tomorrow.

This sounds great. I'll bring my router and modules.
