23 User Guide automatically sets the modems serial baud rate to match your computers and also sets the modems parity. It also clears the modems command buffer. Once youre in terminal mode, enter AT followed by <CR> to check whether your modem is operational.
24 Models MT5600ZDX & ZDXV Figure 2-5. Modem Initialization Setup Other software programs require you enter an initialization string in the software modem setup screen. If this is the requirement in your software application, enter the following command string to initialize your modem: AT&F<cr> .
25 User Guide Troubleshooting Your modem was thoroughly tested at the factory before it was shipped. If you cannot make a successful connection or if you lose data or notice garbled characters during your connection, the modem may be defective. However, it is more likely that the source of your problem lies elsewhere.
26 Models MT5600ZDX & ZDXV The Modem Does Not Respond to Commands 4 Make sure the modem is plugged in and turned on. (See None of the LEDs Light When the Modem Is On.
27 User Guide itself, may use the same COM port, memory address, or interrupt request (IRQ) as your communications port. Be sure to disable any unused ports. To look for address conflicts or IRQ conflicts when using Windows 3.1x, begin in Program Manager.
28 Models MT5600ZDX & ZDXV them, enter ATV1X4 and press ENTER while in terminal mode, or include V1X4 in the modems initialization string. When you dial again, the modem will report the calls progress. 4 Both local and remote modems may be misconfigured, thus encumbering the negotiation process between modems.
29 User Guide the problem may be in your buildings telephone installation. To test the building installation, plug a telephone into your modems telephone wall jack and listen for a dial tone.
30 Models MT5600ZDX & ZDXV the new prefix in the Dial Prefix box. To change the dial prefix in Windows Terminal, select Settings , Modem Commands. To change it in Windows 95 HyperTerminal, select Call , Connect from the menu bar, click Dialing Properties , check This Location has Call Waiting, and select the correct code for your phone service.
31 User Guide Losing Data 4 If you are using data compression and a high speed serial port, set the serial port baud rate to four times the data rate. 4 Your UART may not be reliable at serial port speeds over 9600 bps or 19,200 bps.

66 Models MT5600ZDX & ZDXV Local Analog Loopback Test/V.54 Loop 3 In this test, data from your computer or terminal is sent to your modem's transmitter, converted into analog form, looped back to the receiver, converted into digital form and then received back at your monitor for verification.
67 User Guide the same as the data received on your monitor. If different data is appearing on your monitor, your modem is probably causing the problem, although it could also be your computer. If your modem passes this test, but you are receiving errors while On-line, the remote modem or the phone line could be at fault.
68 Models MT5600ZDX & ZDXV modem. Your modem passes this test if the data entered from the remote keyboard is the same as the data received on the remote monitor. Figure 4-2. Digital Loopback Test (local/manual) 6 . When testing is complete, you may end the test by typing an Escape Sequence ( +++ ) to bring your modem into Command mode.
69 User Guide 4 . Type AT&T6 and hit ENTER. The local modem responds to this command by transmitting an unscrambled marking signal, which causes the remote modem to place itself in Digital Loopback mode. Then the local modem exits Command mode and enters pseudo On-line mode.
