Figure 5.6: Port Parameters Menu; Modem Mode (Port 3 Shown)

When the Port Mode is set to Modem Mode, the menu will include additional prompts (see Figure 5.6), which are used to define the following:

61.Reset String: If necessary, this prompt can re-define the modem reset string, which is sent prior to the Initialization string. (Up to 48 Chars., Default = ATZ).

62.Initialization String: Defines a command string that can be sent to initialize a modem to settings required by your application. (Up to 48 Characters, Defaults: Port 1 through 7 = AT&C1$D2S0=1; Port 8 =ATM0&C1$D2S0=1).

63.Hang-Up String: Although the APS-8/16M will pulse the DTR line to hang-up an attached modem, the Hang-Up string is often useful for controlling modems that do not use the DTR line. (Up to 48 Characters, Default = undefined).

Notes:

•When communicating with the APS-8/16M via modem, communication parameters will not be changed until you exit from command mode and discontinue the modem connection to the unit.

•For a list of basic AT commands for the Internal Modem, please refer to Section 6. For a complete listing of all available AT commands and S-Registers, please refer to the "MT5634 Modem AT Command Set" document in our User’s Guide Archive at the WTI web site: http://www.wti.com/guides/guidarch.htm.
