I try for example the simplest command, �IDN?�, in HyperTerminal or a similar program to get feedback from HP power supply E3631A. But I don�t get any response. After a while I get �Input buffer overflow� on the instrument display, so I seem to have contact. I have the correct baud rate and settings, cause if I change the baud rate on my computer, I get �RS-232 framing error�.
Neither do I get the �OUTP ON� to work.
What do I do wrong??
