Modem Basics

Result code framing

Every command will return a result code unless the Quiet
command is enabled. If Quiet is on (

ATQ1

, see page 102) then

neither framing characters nor result code is returned.

A leading

is inserted ahead of the result code if

Verbose is on (

ATV1

, see page 102). 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. For example, the result code

appears

as:

•

if verbose is on

(ATV1)

•

0<CR>

if verbose is off

(ATV0)

When

ATV1

is set and there is an error,

<CR><LF>ERROR<CR><LF>

is sent to the host computer and no

subsequent commands in the command line are processed. If

ATV0

is set, result code

4<CR>

is sent instead.

The

ERROR

(or

) response may be replaced by

+CME ERROR:

<err>

when the command is not processed because of a GSM

radio connection error.

GPS data format

The MP 700 Series GPS sends GPS data out in UDP packets.
The packets contain either:

•

TAIP or NMEA messages

•

Data packets framed according to a Sierra Wireless
protocol called RNAP (Remote Network Access Protocol).

RNAP is described in detail in the

Software Installation, Configu-

ration, and Integration Guide

on the CD that is shipped with the

MP 750 GPS.
