Using US Robotics Modems with LapLink Applications
- Search Again SUMMARY I have a high speed US Robotics modem, and have problems correctly connecting to another modem when I use LapLink. Can you help?
SOLUTION For most US Robotics modems, the default settings should allow LapLink to connect correctly. In some cases, minor modifications are necessary. Before making any changes to the default settings, we strongly recommend that you confirm that the modem has the most recent drivers installed. Drivers are available from 3Com's web site.
With all US Robotics modems, we've found that either of these configurations has resolved communications problems with LapLink.
Modifying the Windows (TAPI) setup
- From LapLink's Options menu, click Port Setup.
- Click to highlight the Windows modem, and then click Configure.
- Click Properties. On the General tab, lower the speed to 38400 until the connection is successful. (Then raise the baud rate to the highest possible speed that maintains a connection)
- Click the Connection tab, then the Advanced button.
- Remove the check mark from Compress Data and/or Use Error Correction.
- Click on OK twice, then Close twice.
- Retry the LapLink connection.
Note: LapLink uses it's own error correction and data compression protocols, so the user won't suffer performance decreases or risk the integrity of the file copy. Also, these configuration changes are limited to LapLink and will not affect any other communications application.
Using LapLink's Legacy setup. This setup is not available for computers running Windows NT or Windows 2000
- From LapLink's Options menu, click Port Setup.
- Click to highlight the Windows modem, and then take note of the COMx port where the modem is installed. This information is in the Current Port Status window
- Remove the check mark from Enable Port and disable the Windows modem.
- Click the correct COMx port. Change Type to Modem, then click Configure.
- Click Customize, then New.
- Replace User-defined modem with the name for your modem.
- Click in the Initialization field, and clear out the current contents. Scroll right and left to confirm that the field is empty.
- Type one of the following initialization strings. Type them exactly as they are written here. Try them in this order.
^M~AT&F1E0S12=0^M
^M~AT&F1E0&K3&M0S12=0^M
^M~AT&F1E0&K0&M0S12=0^M
Note: Use the numeric 0, not the letter O in all of these strings.
- Click OK. Change the speed to 38400 until the connection is successful. Then raise the baud rate to the highest possible speed that maintains a connection.
- Click OK, then click Enable Port.
A warning message appears about modems that are controlled by Windows TAPI will appear. This message means that while LapLink is in memory, it will have complete control of the modem. When LapLink is shutdown, the modem will be available for any other application.
Another message concerning security settings will appear. Answer this, as you require.
If the port enables, then try the LapLink modem connection again.
If the port does not enable, confirm the following:
- that the Windows modem has been disabled
- the correct COMx port was selected
- the initialization string was typed correctly
- that no other communication applications are currently open
