APS-8M / APS-16M Asynchronous Port Switches; User’s Guide
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
