Detailed Description

The modemclient implements methods for connecting to and communicating with a remote host using a modem.

Constructor & Destructor Documentation

modemclient()

modemclient::modemclient

(

)

Creates an instance of the modemclient class.

~modemclient()

virtual modemclient::~modemclient ( )

virtual

Deletes this instance of the modemclient class.

Member Function Documentation

close()

bool modemclient::close ( )

virtual

Hangs up the modem and closes the device.

Returns true on success and false on failure.

Reimplemented from filedescriptor.

connect()

int32_t modemclient::connect ( )

virtual

Dials the modem and attempt to establish a connection. If the connection fails, it will retry, for a total of "tries" attempts, waiting "retrywait" seconds between each attempt.

Setting "tries" to 0 will cause it to try to connect indefinitely. Setting "retrywait" to 0 will cause it to try to connect over and over as fast as possible (not recommended).

Each attempt to connect will wait "timeoutsec" seconds and "timeoutusec" microseconds for the connect to succeed. Specifying -1 for either parameter will cause the attempt to wait until the underlying protocol times out which may be up to 2 minutes.

Returns RESULT_SUCCESS on success and RESULT_ERROR on failure.

Reimplemented from client.

getConnectScript()

const char* modemclient::getConnectScript

(

)

Returns the connect script (usually a set of AT commands) that connect() will send to the modem during a connect attempt.

getCustomAtCommands()

const char* modemclient::getCustomAtCommands

(

)

Returns the set of custom AT commands that will replace the substitution variable in the connect script, if the connect script contains this variable.

getDisconnectScript()

const char* modemclient::getDisconnectScript

(

)

Returns the disconnect script (usually a set of AT commands) that close() will send to the modem during close.

getPhoneNumber()

const char* modemclient::getPhoneNumber

(

)

Returns the phone number that will replace the substitution variable in the connect script, if the connect script contains this variable.

setConnectScript()

void modemclient::setConnectScript

(

const char *

connectscript

)

Sets the connect script (usually a set of AT commands) that connect() will send to the modem during a connect attempt. The connect script may contain and substitution variables, which will be replaced with whatever values are set by setCustomAtCommands() and setPhoneNumber().

setCustomAtCommands()

void modemclient::setCustomAtCommands

(

const char *

customatcommands

)

Sets a set of custom AT commands that will replace the substitution variable in the connect script, if the connect script contains this variable.

setDisconnectScript()

void modemclient::setDisconnectScript

(

const char *

disconnectscript

)

Sets the disconnect script (usually a set of AT commands) that close() will send to the modem during close.

setParameters()

void modemclient::setParameters ( dictionary< const char *, const char * > *  cd )

virtual

Queries "cd" for "device", "baud", "connectscript", "phonenumber", "disconnectscript", "retrywait" and "tries" and configures this instance to use the results when connect() is called.

Reimplemented from client.

setPhoneNumber()

void modemclient::setPhoneNumber

(

const char *

phonenumber

)

Sets a phone number that will replace the substitution variable in the connect script, if the connect script contains this variable.
