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. Loop Current Sense, input, active High, TTL/CMOS. LCS provides an input to the modem from an external loop current sensor. The Loop Current Sensor may be required for some applications in which the modem shares a telephone line with a telephone handset. 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 ...
