26 Basic Modem Operation

Unix Software Tips

In order to use your ZyXEL modem from a terminal or an X-Windows

application, you need a program such as Minicom or Seyon.

If you wish to make use of your ZyXEL modem's special features,

special gettys such as mgetty or vgetty are needed. These programs are

available from several ftp-sites. Some archives also contain source files.

You should suppress the modem's result code to (ATQ1) because

some applications may be confused by them.
