Reading a Parameter
To read the value of a particular setting, issue the command, with no
parameter. The modem will return the value followed by an “OK”. The
modem’s OK response is:
The value in ASCII decimal format.
A <CR> <LF> (<CD> = ASCII 0D, <LF> = ASCII 0A).
An “O”, “K”, <CR>, and <LF> sequence.
For example, if the user enters the command to read the
FireLine’s
modem address and its address was 1234, the user would issue the
following command:
ATDT
<cr>
and the modem will respond with:
1234
<
CR
> <
LF
>
CONFIG Button
If certain parameters within the modem are modified in a manor that causes
the modem to cease functioning or if the user cannot enter the command
mode via the “+++” method described above, there is a small push button
internal to the
FireLine
modem to assist. This CONFIG button may be
pressed at any time, and forces the modem into a know operational state.
The CONFIG button is located inside the modem. Remove the rear cover,
exposing the two circuit boards. The button is in the center of the lower circuit
board as shown below.
The default setting that the modem will revert to when the CONFIG button are
pressed are:
1. Serial port 9600 baud, 8 data bits 1 stop, no parity
2. ATCT setting set to 60000 (60 second time-out)
Even though the serial baud rate reverts to 9600 baud when the CONFIG
button is pressed, it will revert back to the ATBD setting programmed into the
modem once the Command Mode is exited.
