NAME

SYNOPSIS

9       atinout input_file|- modem_device output_file|-
10       atinout --version
11       atinout --usage
12       atinout --help

DESCRIPTION

15       Atinout reads a list of AT commands. It sends those commands one by one
16       to the modem, waiting for the final result code for the currently  run‐
17       ning  command  before continuing with the next command in the list. The
18       output from the commands is saved.
19
20       Notice that atinout is strictly about sending AT commands only; it can‐
21       not  be  used  for  AT commands that expect additional input data (e.g.
22       AT+CMGS etc).
23

FILES

25       Atinout expects input_file to be a list of AT command to be run. If the
26       file name - is used then standard input is read.
27
28       Although the above states a list of AT commands it is actually not just
29       a list of command but more generally a list of AT command  lines.  How‐
30       ever  the  rest of the man page will just refer to AT commands; running
31       several commands in one command line offers no benefits, and if one  of
32       them  fails you have no idea of which one failed. So unless maybe for a
33       single run on the command line  (see  EXAMPLES),  I  recommend  against
34       putting more than one command on each command line.
35
36       And  if  the distinction between AT command and AT command line was not
37       something you were deeply familiar with you should read the  ITU  V.250
38       specification  about AT commands. In fact, unless you already have read
39       V.250      before,      you      absolutely      should      go      to
40       http://www.itu.int/rec/T-REC-V.250-200307-I/en and do so right away.
41
42       The  modem  is  identified  with  modem_device (e.g. /dev/ttyS0 (COM1),
43       /dev/ttyACM0 (USB phone serial interface), ...). No  serial  configura‐
44       tion (e.g. speed, parity) is done before opening the device.
45
46       The responses from the AT commands are written to output_file, or stan‐
47       dard output i the file name - is given.

OPTIONS

50       The following list of options are supported:
51
52       -h, --help
53              Prints explanation and gives an example on usage.
54
55       --usage
56              Prints information about arguments and options.
57
58       --version
59              Print version information. If this is  the  only  option  given,
60              also prints copyright/licensing information.
61

EXAMPLES

63       Check that the modem is connected and alive.

69           OK
70           $
71
72
73
74       Hang up any calls.
75
76
77
78           $ echo ATH | atinout - /dev/ttyACM0 -
79           ATH
80           OK
81           $
82
83
84
85       Query how many entries the phone book has for ME storage.
86
87
88
89           $ echo ´AT+CPBS="ME"; +CPBR=?´ | atinout - /dev/ttyACM0 -
90           AT+CPBS="ME"; +CPBR=?
91
92           +CPBR: (1-7000),80,62
93
94           OK
95           $
96
97
98
99       Backup  all  phone  numbers. This will most likely not be the same as a
100       full backup of all contact information, but at least the names and num‐
101       bers are saved which is the most vital information.

119       List  current calls. The information text format is (see 27.007 for de‐
120       tails):

BUGS

146       Atinout does not support reading response lines longer than 4095  char‐
147       acters.
148
149       Atinout  does  not  do any serial port configuration, it just opens the
150       device as is.
