virtual bool DUNE::Hardware::BasicModem::handleUnsolicited ( const std::string &  str)
inlineprotectedvirtual

Handle unsolicited or asynchronous commands.

Parameters
[in]strcommand string.
Returns
true if command was handled, false otherwise.
bool DUNE::Hardware::BasicModem::isBusy ( void  )

Test if the modem is busy.

Test if ISU is busy performing an SBD session.

Returns
true if the modem is busy, false otherwise.
true if ISU is busy, false otherwise.

References m_mutex.

bool DUNE::Hardware::BasicModem::isCooling ( void  )

Test if the modem is cooling down.

Test if ISU is cooling down.

Returns
true if the modem is cooling down, false otherwise.
true if ISU is cooling down, false otherwise.

virtual bool DUNE::Hardware::BasicModem::isFragment ( const std::string &  str)
inlineprotectedvirtual

Test if command is not complete (i.e.

is a fragment). This method is useful when the protocol allows mixing ASCII with binary data.

Parameters
[in]strcommand string.
Returns
true if command is a fragment, false otherwise.
