GSMCTL(8)

NAME
gsmctl - GSM mobile phone control program

SYNOPSIS
gsmctl [-b baudrate] [--baudrate baudrate] [-d device] [--device device] [-h] [--help] [-I init string] [--init init string] [-v] [--version] [-X] [--xonxoff] -o operation | --operation operation | parameters

DESCRIPTION
gsmctl can request information from or perform operations on an GSM mobile phone.

gsmctl attaches itself to the device given on the command line (usually an GSM modem) using the specified baudrate. If no device is given, the device is used. If no baudrate is given, a default baud rate of 38400 is used.

gsmctl can be used in to modes: If no --operation option is given the parameters specify the status information to be retrieved from the mobile phone. See the section STATUS INFORMATION for more details. If an --operation option is given the requested operation is performed on the mobile using the parameters. See the section OPERATIONS for more details.

Error messages are printed to the standard error output. If the program terminates on error the error code 1 is returned.

OPTIONS

-b baudrate, --baudrate baudrate
    The baud rate to use. Defaults to 38400.

-d device, --device device
    The device to which the GSM modem is connected. The default is /dev/mobilephone.

-h, --help
    Prints an option summary.

-I init string, --init init string
    Initialization string to send to the TA (default: "E0"). Note that the sequence "ATZ" is sent first.

-o operation, --operation operation
    This option is used to perform an operation on the mobile phone. Refer to the section OPERATIONS for more information on the available operations and the parameters required for each operation.

-v, --version
    Prints the program version.

-X, --xonxoff
    Uses software handshaking (XON/XOFF) for accessing the device.

STATUS INFORMATION
If called without the --operation option gsmctl prints out default mobile phone status information as specified by the parameters described below:

ALL Prints all available information.

BATT
    Prints out information about the current battery status. Two lines of the form "<BATT0> text" and "<BATT1> charge" are printed. Text may be of "0 ME is powered by the battery", "1 ME has a battery connected, but is not powered by it", "2 ME does not have a battery connected", or "3 Recognized power fault, calls inhibited". Charge is a number in the range 0..100 where 0 means that the battery is empty or not connected and 100 means full charge.

BITERR
    Prints information about the current bit error rate. The output is of form "<BITERR0> value" where value can be of 0..7, 99 (99 means not available or not detectable).

CLIP
    This option prints a line of the form "<CLIP0> on" if caller line identification is turned on in the network, "<CLIP0> off" otherwise.

CSET
    Display info about charsets. The output is in the form "<CSET0> available" and "<CSET1> current", which describes the charsets available and which is current.

CURROP
    Prints information about the current operator. The output line has the form "<CURROP0> Long name: 'xxxx' Short name: 'yyyy' Numeric Name: zzzz".

FLCAP
    Prints out the two-letter names of available facility locks. The meaning of standardized facility lock names is as follows:

    CS  Lock control surface (eg. phone keyboard)

    PS  Lock phone to SIM card (mobile phone asks password when other than current SIM card inserted)

    SC  Lock SIM card (SIM asks password in mobile phone power-up and when this lock command issued)

    AO  Barr all outgoing calls

    OI  Barr outgoing international calls

    OX  Barr outgoing international calls except to home country

    AI  Barr all incoming calls

    IR  Barr incoming calls when roaming outside the home country

    NT  Barr incoming calls from numbers not stored to TA memory

    NM  Barr incoming calls from numbers not stored to mobile phone memory

    NS  Barr incoming calls from numbers not stored to SIM memory

    NA  Barr incoming calls from numbers not stored in Any memory

    AB  All Barring services (FIXME)

    AG  All outGoing barring services (FIXME)

    AC  All inComing barring services (FIXME)

    FD  SIM fixed dialling memory feature (if PIN2 authentication has not been done during the current session, PIN2 is required as <passwd>)

    Note that mobile phones may implement facility locks not documented here.

FLSTAT
    Prints information about the status of facility locking in the mobile phone. For each facility a line of the form "<FLSTATn> 'facilityname' classes" is printed. The classes may be "Voice", "Data", and/or "Fax" depending on the class for which the facility is enabled. If "unknown" is printed out this means that the TA is not able to report the status. If the facility is not enabled for any class, no class identifier is printed. See FLCAP for information about the available two-letter names of facility locks.

FORW
    Prints information about call forwarding enabled in the mobile phone. For each combination of reason (UnconditionalReason, MobileBusyReason, NoReplyReason, and NotReachableReason) and class (Voice, Data, and Fax) a line of the form "<FORWn.m> reason class number: xxx subaddr: yyy time: zzz" is printed. The time is the number of seconds to wait before forwarding in case of NoReplyReason.

ME  Prints manufacturer, model, revision, and serial number of the mobile phone (ME = mobile equipment). Output lines are numbered from "<ME0>" to "<ME3>".

OP  Prints information about the currently available mobile network operators. For each operator an output line of the form "<OPn> status Long name: 'xxxx' Short name: 'yyyy' Numeric name: zzz" is returned where status may be of:

    unknown
        The status of the operator is unknown.

    current
        This is the currently selected operator.

    available
        This operator is available for selection.

    forbidden
        This operator is not available for selection, ie. not accessible with this SIM card.

PW  Facilities in the mobile phone may be protected by passwords (ie. PINs or PUKs). This option prints out lines of the form "<PWn> 'facilityname' len" for each facility for which a facility lock password exists. See FLCAP for information about the available two-letter names of facility locks.

SCA Reports the default SMS service centre address currently set in the mobile phone.

SIG Prints information about the current network signal strength. The output is of the form "<SIG0> value". Following values are possible:

0   -113 dBm or less

1   -111 dBm

2...30
    -109... -53 dBm (in steps of 2 dBm)

31  -51 dBm or greater

99  not known or not detectable

OPERATIONS

dial number
    Dials number. After dialling gsmctl waits for a <CR> keypress to terminate.

forw mode reason number [facilityclass] [forwardtime]
    Changes the call forwarding behaviour in the network. mode can be any of:
        disable Call forwarding is disabled.

        enable Call forwarding is enabled. The call forwarding reason, number, and (optionally) forwardtime must be registered beforehand.

        register This registers the call forwarding reason, number, and forwardtime in the network.

        erase This is the counterpart to register. It erase the call forwarding info in the network.

    reason can be any of:
        unconditional This applies to every call.

        mobilebusy The mobile phone is busy.

        noreply The call is not answered in forwardtime seconds.

        notreachable Mobile phone cannot be reached (ie. switched off).

        all This refers to all forwarding reasons.

        allconditional This refers to all conditional forward reasons (mobilebusy, noreply, notreachable).

    number is the number the incoming call is forwarded to. See the explanation for lock operation for the meaning of facilityclass. The default for forwardtime is 20 seconds if omitted. forwardtime can be in the range 1..30.

lock facility [facilityclass] [passwd]
    Locks the named facility. Use gsmctl flcap to get a list of supported facilities. The facilityclass can be any of:
        all Voice, data, and fax.

        v vf vd f fd d Any combination of voice, data and fax.

    The default is all if facilityclass is omitted. The passwd is password for the facility. If no password is given this parameter can be omitted.

setop opmode numericname
    Sets the current operator to numericname. Use gsmctl op to get a list of operators with their numeric codes. opmode can be any of:
        automatic

        manual

        deregister Deregister from network.

        manualautomatic If manual selection fails, automatic mode is entered.

setpw facility [oldpasswd] [newpasswd]
    Sets the password for the facility. If one of the passwords is omitted this means that the facility has no password protection. Passwords are PIN1, PIN2, PUK etc.

setsca service centre address
    Sets the default SMS service centre address.

unlock facility [facilityclass] [passwd]
    This is the reverse operation to lock. See above for a description of the parameters.

EXAMPLES
The following invocation of gsmctl prints out all available status information for the mobile phone connected to /dev/mobilephone
