C-Kermit UNIX, VMS, etc:
and Kermit 95 for Windows 9x/NT/2000/XP:
can dial beepers and can send both numeric pages and alphanumeric pages. Pagers can be dialed not only through a modem that is connected to a serial port on the computer where Kermit is running, but also through modems mounted on TCP/IP "reverse terminal servers".

Beepers and numeric pagers are dialed using a special form of the DIAL command that does not require the call to be answered with a carrier signal. Example:
  set modem hangup-method modem-command ; (if necessary)
  set modem type usrobotics  ; Substitute actual modem type
  set line /dev/ttyS0        ; Substitute actual device name
  set speed 2400             ; Try other speeds if you want
  pdial 7654321@             ; Substitute actual phone number
  clear dial-status
(this dials a beeper), or to dial a numeric pager and leave a message, as above but:
  pdial 7654321@123456#

The SET MODEM HANGUP-METHOD tells Kermit how to make your modem hang up the phone call. In C-Kermit 7.0 and earlier, the default hangup method is MODEM-COMMAND, meaning "pause 1 sec, send +++, pause one sec, send ATH0 and carriage return". Starting with C-Kermit 8.0, the default method is RS232-SIGNAL, meaning the computer should turn off the port's DTR (Data Terminal Ready) signal for half a second. If one of these doesn't work, try the other.

If your modem does not support the "wait for quiet answer" feature (@), you can use commas to force a pause:

  pdial 7654321,,,,123456#

However, in this case, the modem will say OK even if the line is busy, and therefore Kermit has no way of knowing if the call succeeded or failed (and therefore automatic redialing in case of failure will not work).

In case you're not familiar with Kermit's automation features, here's how to turn the above procedure into a script that you can run with a single command from the shell prompt. CD to some directory that's in your PATH and that you have write access to and create a file called ring (or any other name you wish) that looks something like this:

  #!/usr/local/bin/kermit +
  if ( < 2 \v(argc) ) exit 1 Usage: \%0: phone-number [ message ]
  set modem hangup-method modem-command
  set modem type usrobotics
  set line /dev/ttyS0
  set speed 2400
  pdial \%1@\%2
  if fail exit 1
  exit 0

\%1 and \%2 are the command-line parameters. The top line must specify the path of the Kermit executable.

Now give the file execute permission:

  chmod +x ring

Now you can use it to dial any number, just as if it were a regular Unix command:

  ring 7654321            (Just dials the number)
  ring 7654321 1234567    (Dials the number and then leaves a message)

Test numeric paging applications thoroughly. They work only as well as your modem, and most modems were not designed with paging in mind. For a fully elaborated numeric paging script, CLICK HERE.

Alphanumeric pages can be sent in various ways:
