The AR signal goes high when ever the modem is in the on-hook state. It can be connected to an external relay to switch control of the telephone line between the modem and an auxiliary handset when. Received Data, Output, TTL. Serial data output to the host. A logic "High" on RXD represents a "mark" and a logic "Low" represents a "space". No Internal Connection Data Terminal Ready, Input, active Low, TTL. The "AT&D" command sets the function of DTR. The default, AT&D2, requires the host to assert DTR to permit a modem link. The modem drops the call in progress if DTR is revoked and will not connect until DTR is reasserted. No Internal Connection Clear to Send, Output, active Low, TTL/CMOS. CTS provides the flow control output from the modem when hardware flow control is selected. The modem revokes CTS when the modem's input buffer is full. The modem reasserts CTS when the buffer can accept more data without a buffer overflow. No Internal Connection Transmit Data, Input, TTL. Serial data input from the host. A logic "High" represents a "mark" and a Low represents a "space", TTL. Request to Send, input, active Low, TTL. The XE3314L uses RTS for hardware flow control. When RTS is revoked; hardware flow control is enabled, and the modem will not place data on RXD. No Internal Connection Ring Indicator, Output, active Low, TTL. When low indicates the modem is recei...
