Quatech user manual ESC-100M only

The AUXIN and AUXOUT signals on the RJ-11 connector must be determined as well. Either CTS or DSR may be received on AUXIN. Either RTS or DTR may be transmitted on AUXOUT. The decision of which signals to use is made separately for each channel as shown in Figure 22 below.

The Ring Indicator (RI) signal is tied permanently to DSR.
