LAVA LINK-650 WINDOWS 3.1/3.11 DRIVER INSTALLATION INSTRUCTIONS
---------------------------------------------------------------



Notes
-----

1. The Lava Link-650 device driver and Lava Com Port Utility may be used with any version of Windows 3.1 and Windows for Workgroups 3.11. 
++++++++++++++ DO NOT USE THIS DRIVER FOR WIN95 OR WINDOWS NT +++++++++++++++++

2. The Lava Link-650 device driver makes certain changes in your SYSTEM.INI file. It is usually a good idea to save your current SYSTEM.INI file under another name before installation of the Link-650 software.

3. The Lava Link-650 installation software looks for the original Microsoft Com Driver for Windows 3.1/3.11 and replaces it. If you have previously replaced this driver with another driver (e.g. TurboComm, KingComm, etc.), these replacement drivers should be removed.



First-Time Installation
-----------------------

1. Configure the jumpers on the Lava Link-650 board for an unused Com Port I/O address & unused IRQ. If you are unsure which Com Ports & IRQ's are unused, consult your PC documentation, or MSD (see Microsoft Documentation). Please note, that MSD is not accurate when reporting IRQ assignments for Com Ports - Com Port will always be shown as using IRQ 3 & IRQ 4.

2. Install the Lava Link-650 board into your PC. Choose any unused ISA slot.

3. Start Windows. From Program Manager, select File, then Run, and type in the path in which the SETUP.EXE file can be found.

4. SETUP will install the Lava Com Port Utility and create a separate icon in Program Manager for it. Click the Com Port which corresponds to your Lava Link-650 and select 650 under UART type. Select the IRQ which corresponds to your hardware configuration, and then procede to configuring the various settings for the Link-650. Help with each setting can be accessed through the small help buttons.

5. You may choose to use the Lava Com Port Utility to run any other Com Ports which may be installed in your PC. Do this by double-clicking the appropriate Com Port and configuring it accordingly. To verify if you have a 450 or 550 UART type, run MSD from DOS and select <C>om Ports. 

6. Because any changes which you make to your configuration must be saved in the SYSTEM.INI file, you must restart Windows each time you modify the Lava Com Port Utility in order for changes to take effect.
