------------------ Additional Follow-up Comments ----------------------------
The problem seems to be that the default timeout for TSerial::Send of 1 second 
is not enough. Changing the timeout to 3 seconds seems to eliminate the 
problem. The proposed fix is to increase the default value in Serial.h from 1 
to 3.

Summary:  Error programming AT90S8535 in STK500

Original Submission:  I am trying to program an 8535 in an STK500 developement 
board using uisp. The flash erases successfully. However, after programming the 
STK500 board is hung (status light is red)

uisp exits with an error talking to the programmer.

After power-cycleing the STK500, the chip is actually programmed correctly and 
useable (though I can't guarantee this will be the case for every program, just 
the one I tried last night).

Interestingly, if I use -dpart=AT90S8515 instead of 8535 (on the same chip, it 
still claims to be programming an 8535, doesn't generate an error, but the 
programmed chip does not work.
