Console Mode
In Console Mode the Configuration Menu can be accessed from a PC
by connecting its RS-232 serial port to the ESP901 serial port or
ESP902 Serial Port 1. Since the computer is a DTE device, and the
serial ports are configured as DTEs (with DB-9M connectors), a null
modem crossover cable must be used.
In Console Mode the default serial port settings are: 9600 baud, 8 data
bits , No parity , and 1 stop bit . From Windows, HyperTerminal with
VT100 terminal emulation can be used for Console Mode
configuration.

Ground and is configured as a DTE, like a computer. Signals are single
ended and referenced to Ground. To use handshaking, Flow Control
must be set to RTS/CTS during Configuration.
