Appendix A AT Commands Use this command to control the modem's response to receiving a remote modems carrier signal. Data carrier detect (DCD) is a signal from the modem to the DTE indicating that the carrier signal is being received from a remote modem. The modem typically turns off DCD when it no longer detects the remote modems carrier signal. &C0 &C1 Modem ignores the state of the carrier from the remote modem. DCD remains on at all times. Modem turns on DCD when the remote modem's carrier signal is detected and turns off DCD when the carrier signal is not detected (default). &D-Data Terminal Ready (DTR) Control Use this command to set how the soft modem responds to the DTR signal. &D0 &D1 &D2 &D3 The soft modem ignores the true status of DTR and treats it as always on. Use this selection only if the computer does not provide DTR to the modem. If the DTR signal is not detected while in on-line data mode, the modem enters command mode, issues the OK result code, and remains connected. If the DTR signal is not detected while in on-line data mode, the modem disconnects (default). Reset modem on the on-to-off DTR transition. &G-V.22 bis Guard Tone Control Use this command to select which guard tone, if any, the modem will send while transmitting in the high band (answer mode). This command is only used in V.22 and V.22 bis mode. This option is not used in North America; it is for international use only. &G0 &G1 &G2 Disables guard tone (default). Selects 550 Hz guard tone. Selects 1800 Hz guard tone. &J-Auxiliary Relay Option This command is supported to ensure compatibility with communications software that issues the J0 command. &J0 The auxiliary relay is never closed (default). &K-Local Flow Control Selection Use this command to set the soft modem flow control method. 39
