The 7400B data module can be used at a remote site as a dedicated service
device to answer incoming data calls, send data to a remote end device, and then
hang up. For example, you might wish to provide access to a printer from a
remote site. The following is a typical command line you might use for setting up
this operation (spaces are used here for readability, but are not required):
1. at &c1 &d2 q1 s0=1 &w0 &y0
where:
■
at puts the modem in command mode
■
&C1 sets the Data Carrier Detect (DCD) circuit of the data module to
operate according to the EIA standard
■
&D2 sets the data module to go on hook when an on-to-off transition
is detected on the Data Terminal Ready (DTR) input, disconnecting
the call
■
Q1 turns off the result codes that would be the normal responses of
the data module to commands that it receives.
■
S0=1 turns on the automatic answer feature and causes the data
module to answer an incoming data call on the first ring
■
&W0 causes the current configuration to be stored in profile 0
■
&Y0 selects the configuration stored in profile 0 to become the
current configuration each time the data module is powered on
Configuring the 7400B for remote administration
1. At the command prompt of your terminal-emulation software or terminal,
enter at&c1&d2&s1s0=1&w0&w1&y0
where:
■
at puts the modem in command mode
■
&c1 tells the modem to respond to DCD
■
&d2 tells the modem to respond to DTR
■
&s1 tells the modem to respond to DSR
■
s0=1 tells the modem to auto answer on the first ring
■
&w0 tells the modem to save changes in profile 0
■
&w1 tells the modem to save changes in profile 1
■
&y0 tells the modem to use profile0 after a power failure
