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? :)
