I'm using cu on another FreeBSD/i386 machine to connect to one of the other serial ports of the Avocent. The CPS offers a "port break" command for creating a break condition on an attached serial port, but that doesn't trigger anything on the receiving FreeBSD machine. Using a direct serial connection (just 2x3, GND) between the machines works, though. I realize this being quite a long shot -- Someone ever used such a box successfuly for the purpose ? MfG CoCo
