Console Port Signals
Table 3-1
lists the signals used on the console port. The console port does not support modem control or
hardware flow control. Both Data Set Ready (DSR) and Data Carrier Detect (DCD) signals 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 requires a straight-through EIA/TIA-232 cable.
