       imontty - display status of all ISDN lines


       imontty [ phonebook ]


       imontty  displays  the  status  of  all  ISDN  lines.  No  options  are
       supported. Read access to /dev/isdninfo is required.

       It is possible to supply the name of a phonebook  file.  The  phonebook
       file has the following format:

          number<tab>name for number

       The  number  must  be  the first thing on the line (no leading spaces).
       The name is separated from the number by a tab.  Lines beginning with #
       are ignored, as are empty lines.

       The output is similar to this:

       ISDN channel status:

       Channel                 Usage Type  Number
       line0                   Out   Net   0204229700
       line0                   Off

       Usage is one of Off(line), Out(going), In(coming) or Excl(usive).

       Type  is  one of raw (raw device), Modem (modem/tty emulation), Net (IP
       interface), Voice (voice call) or Fax (fax transmission).

       Number is either the called party’s number (outgoing)  or  the  calling
       party number (incoming).
