It's a special cable. The RJ-45 at the other end is NOT Ethernet! Do NOT plug it into a network card as you will likely blow it up. The RJ-45 plugs into your switch's console port. So you need an RS-232 port on your FreeBSD machine to connect to it. Hence the need for a USB -> RS-232 converter.ORTO-DOX said:Is that cable not for connecting to the RS232 port? Or is it not supported in FreeBSD?
