TRINGS
You can configure the Switch to automatically dial a remotely located management
terminal in case of an alarm or a status change resulting from local pushbutton
operation. The unit will also “hang up” the modem when the transmission is
completed.
• The command D<CR> will display the current dial and hang-up strings.
• The command DD (dialstring)<CR> will change (store) the dial string to
[dialstring]. The “backslash convention” must be used to enter control
characters. For example, “\M” is Carriage Return.
DDATTD5551212\M<CR> will cause “ATTD5551212<CR>” to be stored as the
dial string.
