iM1000-Data Modem
Activate DTR Monitoring
By factory default, the DCE does not monitor the DTR line of the DTE/
DCE physical connection. Many communications programs use the DTR
line to terminate ongoing PPP/SLIP sessions. Therefore, you must activate
DTR monitoring in the DCE.
Activate DCD Management
By factory default, the wireless modem keeps the Data Carrier Detect
(DCD) line of the computer-to-modem physical connection active at all
times. Some communications programs monitor this line to determine the
status of the connection. To promote compatibility with these programs,
enable DCD management in the modem.
Set the Computer’s IP Address
You must inform the modem of the computer IP address to establish a SLIP
or PPP connection between the modem and the computer. The following
example uses the IP address 173.56.1.1. Substitute this value with the
address supplied by your system administrator or service provider.
