P.S. - It also works well with a Bootloader.
use the ICSP interface to install the TinyBootloader or an equivalent with
the ICSP Dat and Clk lines set at the Rx and Tx lines and you have a nice
development device with Programming, Debugging and Communications all
achieved via a USB/Serial adapter - Great to hand out to students or use
for casual experimenting as well as in target applications.
Cheers
