No, in most cases i just switch plugs. It may be time consuming, but so far
hadnt have any problems.
Confess that i never had 1000 PICs to update at the same time, like Wouter
has to do.

When using the USART for external equipment, for most of the tests i just
use a terminal software to input data and get feedback.

True! very true!  I may give it a try one i finish what im doing now.

I particularly like the Debugging feature of it, its quite helpful. Specialy
to avoid the ICE.
