## Detailed Description

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

## Constructor & Destructor Documentation

## ◆ modemclient() [1/2]

modemclient::modemclient | ( |  | ) |

Creates an instance of the modemclient class.

## ◆ modemclient() [2/2]

modemclient::modemclient | ( | const modemclient & | m | ) |

Creates an instance of the modemclient class that is a copy of "m".

## ◆ ~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.

## ◆ initialize() [1/2]

void modemclient::initialize | ( | const char * | device,
|  | const char * | baud,
|  | const char * | customatcommands,
|  | const char * | connectscript,
|  | const char * | phonenumber,
|  | const char * | disconnectscript,
|  | uint32_t | retrywait,
|  | uint32_t | tries
| ) |  |

Initializes the class to use "device", "baud, "customatcommands", "connectscript", "phonenumber", "disconnectscript", "retrywait" and "tries" when connect() is called.

## ◆ initialize() [2/2]

void modemclient::initialize | ( | constnamevaluepairs * | cd | ) |
| virtual

Initializes the class to use "device", "baud, "connectscript", "phonenumber", "disconnectscript", "retrywait" and "tries" when connect() is called.

Reimplemented from client.

## ◆ operator=()

modemclient& modemclient::operator= | ( | const modemclient & | m | ) |

Makes this instance of the modemclient class identical to "m".
