Configuration and Operation
3-4 Issue 2 November 1996
you cannot delete the AT prefix once it is typed. The factory-default backspace
character is an ASCII backspace.
Once you complete a command line by pressing
, the 8400B Plus Data
Module will try to interpret all characters on the command line as valid
commands. If the 8400B Plus Data Module finds a character that is not a valid
command, it will ignore the erroneous character and any remaining characters
on the command line.
Command Acknowledgment
Commands are acted upon immediately and are acknowledged by a result
code. Most commands are acknowledged by OK. This assumes that the result
codes are configured in the verbose form (command V1 is in effect), and are
enabled (Q0 in effect). Another option for configuring result codes is the short or
numeric form. These result codes are set by the V0 command, which would
produce a 0 (zero) instead of the message OK. A final option for result codes is
to disable them (Q1). Refer to Appendix A for descriptions of the V and Q
commands.
Several other result codes may appear on your terminal screen while the 8400B
Plus Data Module is completing a call. The option selected by the X command
controls which of these result codes may appear on the screen of your terminal
(the X command is described in Appendix A). All result codes that may be
returned by the 8400B Plus Data Module are shown in Table 3-2 and in
Appendix E.
