Result Codes
The 56K Softmodem AT command handler responds to commands from the caller
and to activity on the line via result codes. Table 5-1: presents a summary of these
result codes.
Two forms of each result code are available. The long-form, or verbose, response
is given when
V1
is selected, and the short-form, numeric response is given when
V0
is selected. The long-form code is preceded and terminated by the sequence
<CR> <LF>. The short-form is also terminated by <CR>, but it has no preceding
sequence. If result codes are suppressed, nothing is returned to the caller.
