Details:

We're using a stk500 compatible bootloader on the avr128. to program, we
press and hold the reset butten of the embedded system, then start uisp (uisp
sends its sdk500 hello msg) and release the reset button. the bootloader
starts with sdk500 "I'm here" message which triggers uisp to respond
immediately.

For this to work, uisp should not get any garbage data from the last program
run. A simple fix for Serial.C just flushed the Serial Port on opening. I
guess this should not harm anyone else, but helps us a lot (what do you
expect from a freshly opened serial port? :)
