MT3334ZDX/V Owner's Manual

TR

Terminal Ready. When TR is lit, the MultiModemZDX can answer an incoming call. This signal (TR or DTR) provides a means for the terminal or computer to control the MultiModemZDX's connection to the communications channel. A high DTR signal is required by the MultiModemZDX to be able to communicate. The state of the TR LED matches that of the DTR circuit on pin 20 of the RS232/V.24 interface.

EC

Error Correction. This LED is lit when the modem is set for V.42 error correction, and flashes on and off when data compression is activated.

FX

Fax. This LED is lit when the modem is connected in Fax mode.

Is Your MultiModemZDX Ready for Use?

As soon as you have connected power to the modem, if you’re an experienced modem user, you may simply want to check your modem’s settings for data compression, error correction, and so on. You may find that you can get moving quite quickly if you just issue the AT&V<cr> command. This command lists how your modem is currently configured. If you come across a setting you’re unsure of, refer to Chapter 3 of this manual for AT command and S-Register explanations and defaults. If you’re a novice, please continue to the next sections of this chapter.
