CDMA 1xEV-D0 AT Commands Reference Guide (Document S000482B) 14

Result Code Framing

Every command returns a result code unless the Quiet command is enabled. If Quiet (Q) is on (=1), then

there are no framing characters nor any result code returned; the modem is truly silent with respect to

result codes.

A leading <CR><LF> is inserted ahead of the result code if Verbose (V) is on (=1), otherwise there are

no leading characters prior to the ASCII numeral result.

The result code is always followed by a <CR>. There is a trailing <LF> only if Verbose is on. Samples:

V=1 <CR><LF>OK<CR><LF>

V=0 0<CR>
