CallerID


This program is a small Visual Basic example using the MSCOMM.VBX to 
send the appropriate modem commands to enable the Caller ID (CID) functions
of a CID-enabled modem.  Also, the CID service from your phone company 
must be active on the phone line.

Before you execute the program be sure to copy MSCOMM.VBX, MHGLBX.VBX, and
MHRUN400.DLL to your \WINDOWS\SYSTEM subdirectory (or a directory 
in your PATH)!


Files included:
CallerID.EXE    - the Windows program
CallerID.TXT    - this file
CallerID.INI    - INI file to hold program settings
MSCOMM.VBX      - custom control
MHGLBX.VBX      - custom control
MHRUN400.DLL    - run-time module for custom control


Start:
   This command starts the capturing of CID information by sending the 
   appropriate AT extended commands to the modem.  The program will wait
   10 seconds after each command sent to the modem for an "OK".  If an "OK"
   is not received it will assume a COM Port or modem error has occurred and 
   display a message. It also turns off modem answering using ATS0=0.

End:
   This command ends the capturing of CID information and exits the program.

Delete:
   This command will delete any selected records from the CID information
   listbox.

COMPort:
   This button will display another form where you may change the COM Port
   that your modem is connected to.  I mistakenly did not place this function
   in the first version of this program.  Sorry to all you people who 
   downloaded the first one!!!


Other changes:
   I also added a some better COM Port error handling routines.
              

Disclaimer:
   This program took about 2 or 3 hours to complete, that's why alot of
   features are not in it.  It was meant to be a test to see if CID functions
   of Zoom modems were working correctly.  I have the "extended" CID service
   from my phone company which also sends a Name, so I don't know if the 
   parsing routines I use will pick up just the Date, Time, and Number.  I
   have yet to figure out all of the CID codes that the phone service sends
   so if you receive a blank line or just the Date and Time, then the caller
   is probably Private or Unavailable.  I am in process of decoding the messages
   sent so the listbox can be appropriately updated.  I am also planning on
   adding annoucement features (play a WAV file when a certain number calls)
   soon!

Bugs:
   If you encounter any bugs I will be more than happy to fix them and 
   re-submit.  Again, I apologize to everyone who downloaded the first 
   version of this with no COM port selection.
