COM2 for –xxx3 boards have control signals RTS, DTR, DSR, and CTS.

The COM 2 port presents a standard DTE interface on an RJ-45 connector. This port may be used for management or for Passthrough. An RJ-45 to DB9 straight-through cable may be used to connect directly to most serial ports on laptop PCs. The serial port operates at a rate of 9.6Kbps Async, 8-Bit, No Parity. The VBrick appliance comes with a cable to attach this port to a standard 9-pin serial adapter.
