GOT IT!!! It was the termination character!!! Thanks... I used serial & visa before but this never happened. Just setting it to "false" in VISA config serial port.vi solved the problem Thanks a lot again Massimo

I am reading a device with a rs232 interface 4800 baud 8/1/n/1 no handshake control By a probe on bytes at serial port it says 600 - 700 bytes, but the instruction VISA read serial port, with the output of Bytes At Serial Port connected, returns 6-10 bytes and sometimes hangs. Hyperterminal works correctly, bytes not read are in the serial buffer anyone who can help me with some hints? thanks anacche
