Configuration - Screens and Control Fields
Control Fields on the Configuration Screens
Modem Initialization/Configuration
This field is used to enter configuration strings for the modem. It is a
three-line field. Each string has a maximum of 40 characters. Blank
lines will be skipped.
This setting is retained when the instrument is turned off.
To send these strings to the modem, select Send to Hardware under
the Modem Configuration field.
Operating Considerations
An initial string containing the decimal equivalent of the escape
character and the value of the connection time-out is automatically
generated and sent when Send to Hardware is selected. Then the
strings entered in this field are sent.
The first line is blank by default, but can be used to make settings such
as baud rate if your modem is not set to autobaud detection. The second
and third line’s default settings are common modem configuration
strings, but they can be changed if they do not match your modem’s
requirements. (Refer to you modem’s documentation for further
information.)
