RS-232 Control
RS-232 control can be performed using a standard terminal emulation software
application on a PC such as HyperTerminal. The baud rate is 115200, 8 data bits, 1 stop
bit, no parity. The RS-232 port can be connected to a PC serial port using a standard
DB-9 Male-Female “straight through” cable.
After booting, the Controller Card will output the version number in a carriage return
delimited string. The following commands can be used to control the COS chassis via
RS-232 control. The COS is case insensitive. A CR+LF terminator must follow all
commands.
Command Format Description

H <command>
Prints out help on all or specific command.
The “Get Status” mode of the RS-232 port allows for continual display of Controller and
Switch Card states and switches. To use this mode, place the terminal emulator in what
is called “ANSIW” mode and issue the Get Status command “GS”. In “ANSIW” mode,
the COS can control font color and cursor position, allowing for a well-formatted screen
to be frequently updated and yet still be legible.
