       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
