Console Port Signals
Both Data Set Ready (DSR) and Data Carrier Detect (DCD) 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 8 lists the signals used on the
console port. The console port requires a straight-through EIA/TIA-232 cable.
