you cannot delete the AT prefix once it is typed. The factory-default backsp ace
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 vali d
command, it will ignore the erroneous character and any remaining char acters
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 i s 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 sc reen while the 8400B
Plus Data Module is completing a call. The option selected by the X com mand
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.
