Ich hatte mir schon so was gedacht, hab jetzt die wichtigen Meldungen nach vorn gepackt... ;o) Hier mein Beispielcode fuer die Ansteuerung:

' -----[ Program Description ]---------------------------------------------
'
' Example program for RS232 control of RN-Speak via BASIC Stamp controller
' Direct connection, BASIC Stamp outputs 5V - enough to work...

' Connections: BS2             RN-Speak     RS232
'
'              P15 (Tx) ---->  Pin 1 (RX)   DB9.2
'              P14 (Rx) <----  Pin 3 (TX)   DB9.8 not used
'              Vss      -----  Pin 2 (GND)  DB9.5

Rx              PIN     14                      ' serial in from RN-Speak
