Changing Default Parameters
The default values for the other parameters in modem configuration menus rarely need changing. They typically
include the dialing prefix (ATDT for touch-tone service and ATDP for rotary service), the dialing suffix (^M), the
hang-up string (+++) Response then (ATH0^M), and response messages (RING, NO CARRIER, BUSY, etc.).
Communications software with a host mode might include an auto-answer string (AT S0=1^M).
Macintosh Initialization Strings
● To use RTS/CTS hardware flow control with a Macintosh computer, you must use serial cable wired for
hardware control.
● Macintosh 128 and 512 models cannot use RTS/CTS flow control at all. For these models, use the following
string to turn off the default RTS/CTS hardware flow control, turn on XON/XOFF flow control, and ignore
DTR: AT &F X4 &k4 &D0 ^M
● For hardware flow control, use the following initialization string AT &F X4 &K3 &D0 ^M
● Add S0=0 to both strings to disable auto-answer if the MT5600BR-V92 is on a voice line.
To store the initialization string in nonvolatile memory:
1. With your communications software open and connected to the modem’s COM port, type the initialization
string in the terminal window, substituting a carriage return for ^M.
2. Enter AT &W0 <CR>.
When the initialization string is stored, you can use the following string to initialize your modem:
AT Z ^M
Configuring the Modem for Your Country or Region
Different countries have different requirements for how modems must function. Before using your modem,
configure it for country/region in which you are using it. You can use either the Global Wizard or AT Commands
to configure the modem for your country.
Using the Global Wizard
If using your modem with a Windows operating system, use the Global Wizard software to set the country. This
is available through the Multi-Tech Installation Resources site.
Installing the Global Wizard
1. Go to http://www.multitech.com/setup/product.go and select your model from the Product drop down list.
2. Click Software.
3. Click Global Wizard link.
4. Click Run twice. The Global Wizard installer launches.
5. Click Next.
6. Click Yes.
7. Click Next.
8. Click Finish. This completes the Global Wizard installation.
