Enables and disables the modem speaker.
A boolean value which specifies if the modem speaker is enabled.
The ModemSpeaker property determines if the modem speaker is enabled when dialing the remote server. If the property is set to false, the modem will be silent when dialing the telephone number and establishing the connection. Note that setting this property to true will not force the speaker on if the modem hardware has been configured to explicitly disable the speaker.
To disable the speaker, the modem must support changes to the speaker volume. Disabling the speaker is typically done by instructing the modem to set the speaker volume to zero.
