6.2.7 Modem Control<br />
JavaComm is strictly concerned with the handling of a serial interface and the transmission of<br />
data over that interface. It does not know, or provide, any support for higher-layer protocols,<br />
e.g. for Hayes modem commands typically used to control consumer-grade modems. This is<br />
simply not the job of JavaComm, and not a bug.<br />
