DB-25 Console Port Signals and Pinouts
Both Data Set Ready (DSR) and Data Carrier Detect (DCD) are supported on the C7200-I/O,
C7200-I/O-FE, and C7200-I/O-FE-MII and are active when the system is running. The Request To Send
(RTS) signal tracks the state of the Clear
To Send (CTS) input. The console port does not support modem
control or hardware flow control.
Table 3-14 lists the DB-25 console port signals for the C7200-I/O,
C7200-I/O-FE, and C7200-I/O-FE-MII. The console port requires a straight-through EIA/TIA-232
cable.
