- Description
- -----------
- CCLINK and CCLINKjr monitor and display the status of your modem and
- serial port right on your Windows desktop. For you internal modem users,
- CCLINK is invaluable since your modem does not have any status lights, but
- CCLINK does! CCLINK also allows you to talk to your modem and send command
- strings to it. CCLINKjr only monitors your serial ports, but you can run
- multiple instances of it monitoring many ports at once. Think of the fun!
-
-
- How to run CCLINK:
- ------------------
- 1. Use Program Manager's File/New option to create a new program item called
- CCLINK or CCLINKjr. That's it!
-
- 2. If you like, you can set CCLINK.INI options to customize startup options.
- Check out the sample CCLINK.INI that's included. It must be in your Windows
- or Windows for Workgroups directory.
-
-
- Enhancements and General Operation
- ----------------------------------
- CCLINK can input AT commands to your modem ports at speeds of 1200, 2400, 9600,
- 19200, 38400, 57600, and 115K bps.
-
- There are menu options for configuring your modem. The "Modem Stuff..."
- option allows you to use modem reset strings and will accept carriage-return
- terminated strings from a CCLINK.INI file. Default reset strings are used if
- the CCLINK.INI is unavailable or only provides one string.
-
- The "Send AT command" option will send these strings to the serial port.
- When choosing to send both strings at once, there is a hard-coded one-second
- delay between sending the first and second strings.
-
- CCLINK's AT-INPUT allows easy toggling between the AT Command and Monitor
- modes.
-
- The OPTIONS menu allows you to turn terminal echo (duplex) on or off, lower
- DTR or RTS for test purposes, switch between monitoring parallel and serial
- ports, and toggling the "Always On Top" option. Check it out!
-
- CCLINK will inform the user when the COM port is busy or being used. If
- Windows reports that the COM port does not exist, CCLINK will let you know.
-
- Occasionally, CCLINK may report data errors and report an error number
- inside of a message box. These are the following values that may be reported,
- and you may want to record the value for troubleshooting:
-
- 01 /* Receive Queue overflow */
- 02 /* Receive Overrun Error */
- 04 /* Receive Parity Error */
- 08 /* Receive Framing error */
- 10 /* Break Detected */
- 20 /* CTS Timeout */
- 40 /* DSR Timeout */
- 80 /* Carrier Timeout */
- 100 /* Transmit Queue is full */
- 200 /* LPTx Timeout */
- 400 /* LPTx I/O Error */
- 800 /* LPTx Device not selected */
- 1000 /* LPTx Out-Of-Paper */
- 8000 /* Requested mode unsupported */
-
- A value of 18 is two errors: error 10 and error 8 together.
-
- COMMENTS
- --------
- 1. 'M' is displayed if CCLINK is Monitoring the port; 'I' appears if it
- is currently able to input commands. The bps rate only appears when AT
- INPUT ('I') is set.
-
- 2. Double letters will appear if modem ECHO (ATE1) and Duplex are both on.
- Either turn off Duplex in the OPTIONS menu or turn off modem echo (ATE0).
-
- 3. Carriage returns and control characters appear as vertical bars sometimes.
- CCLINK cannot send control characters or the escape key to the modem port.
- Working on it!
-
- 4. After more than 10 lines appear in the AT Window, the next user input
- will clear the window. When maximized, this value is set to 40 lines. This
- can be configured in CCLINK.INI, but changing it is not recommended.
-
- 5. You can dial out to bulletin boards, but you should properly configure
- the modem first, especially at very high speeds. On rare occasions, CCLINK
- may lose control of the modem and you may have to turn CCLINK OFF and then
- ON or re-select INPUT AT Commands so that CCLINK can reinitialize the port.
- You should configure the modem for hardware flow control (AT&K3 or AT\Q3).
-
- 6. Outputting text to the AT Window flashes so the user knows they are
- inputting to the port. This flickering will be eliminated in future
- releases.
-
- 7. CCLINK briefly opens and closes an unused serial port when intially
- brought up. This is required, especially for Windows for Workgroups 3.11
- compatiblity CCLINK uses standard Windows communication function calls
- in order to light the send (SD) and receive (RD) lights, and it should
- have little effect on your application's performance.
