communications package modem initialization string:

The PRO/100 PC Card does not have a built-in speaker. It relies on the
PC Card software to direct signals to the computers speaker. A few
computers do not properly direct the PRO/100 PC Card audio to the
system speaker. The modem will connect and operate normally, but no
sound will be heard. On some PCs you can set the speaker on or off or
change volume levels with a keyboard sequence. See your computer
documentation.
