Thanks Phil. I'll try that. In fact I'm switching back and forth from
T2 to T1, so my current solution is to use two separate .bashrc files
for T2 and T1. When working with T1 code, I use make tmote, then
source ~/T2.bashrc, then make tmote reinstall so I can still use the
new bsl.
As of the serial forwarder, the following is the error message after
the upgrade:

Serial Forwarder Exited Normally
I thought it is the incorrect classpath specified in T2, but after
changing it back things remain the same.
Thanks,
