MODEM PARAMETER SETTINGS
This chapter explains how to view and set various major modem parameters using
the Supreme 2864L CONFIGURATION menu tree. The non-LCD model users can
also consult this menu tree for available parameter options, but must use the equiv-
alent AT command to set the parameter.
The various levels of the CONFIGURATION menu tree are defined here as:
CONFIGURATION menu
submenus
parameter menus
parameter selection
whereby the CONFIGURATION menu is the root of this menu tree. Some submenus,
like STATUS REGISTER, SAVE TO, and RESET, have a direct parameter selection un-
der them and do not have the parameter menu level.
Under the CONFIGURATION menu, there are seven submenus (see also Fig. 5.1):
• TERMINAL OPTIONS (parameters for local DTE connection)
• MODEM OPTIONS (parameters for connection to a remote DCE)
• ERROR CONTROL (how to react to transmission errors)
• AUDIO OPTIONS (controlling the internal speaker)
• STATUS REGISTER (see chapter 8)
• SAVE TO (saving a set of parameters into a profile)
• RESET (loading a profile)
Every submenu screen defines certain parameters of the modem’s operation. Sub-
menu selections are made by using the left and right arrow panel keys. Pressing the
ENTER key will access the parameter menu and pressing the up arrow key (MENU)
will return you to the CONFIGURATION menu.
Parameter Menu
The parameter menu selections are made by using the left and right arrow keys to
move from one selection to another. Pressing the up arrow key (MENU) will return
you to the submenu screen. Press ENTER to go into Parameter Selection. You will no-
tice that a blinking cursor will appear at the left side of the equal sign (=).
