The GRP console port is a DB-25 DCE interface for connecting a DTE terminal
device to the router. Both Data Set Ready (DSR) and Data Carrier Detect (DCD)
signals are active when the router is powered on. The console port does not
support modem control or hardware flow control and requires a straight-through
EIA/TIA-232 cable.
Before you connect a terminal to the console port, check the terminal setting for
the data transmission rate, in bits per second (bps). The terminal transmission rate
setting must match the default rate of the GRP console port, which is 9600 bps.
Set the terminal to these operational values: 9600 bps, 8 data bits, no parity, 2 stop
bits (9600 8N2).
Table 2-3 lists the signals used on the console port.
