Support for ISA Bus I/O: Serial

This program automates the changing of modem DTE rates from 115.2k bps to 230.4k bps. 3Com Impact IQ and Motorola BitSURFR Pro EZ users will find this program particularly useful. These modems require the users to send AT commands to the modem to reset it for 230.4k bps operation, then the properties in Control Panel need to be set, then the properties in Dial-up Networking. The Lava Modem Speed Set program automates all of these operations, and changing speed is now a matter of a single click.

Lava Modem Speed Set currently supports the following external modems:

3Com Impact IQ

Adtran Express XR & XRT

Ascend Pipeline 15

US Robotics Courier I-Modem

Motorola BitSURFR Pro & BitSURFR Pro EZ

  1. Locate the device and model that is having the issue and double-click on it to open the Properties dialog box.

  2. Select the Driver tab.

  3. Click the Update Driver button and follow the instructions.

In most cases, you will need to reboot your computer in order for the driver update to take effect.

Tech Tip: Driver downloads and updates come in a variety of file formats with different file extensions. For example, you may have downloaded an EXE, INF, ZIP, or SYS file. Each file type has a slighty different installation procedure to follow.
