The Four Slot Dock 7-11
2325A137REFGD Revision B 2325 Reference Guide
The 4SLOT.SYS Device Driver
To use terminal-demand mode within a custom application or to use
host-controlled mode, you should have the 4SLOT.SYS DOS device
driver installed on the portable. The 4SLOT.SYS driver extends the
capabilities of the DOS COM driver and provides a programming
interface so that custom programs can request, detect, and drop access to
the 4-Slot Dock communications line. For host-controlled mode, the
4SLOT.SYS driver allows the user to assign a unique name to the
portable that the host can use to control that portable's ability to access
the 4-Slot Dock communications line.
Note: The 4SLOT.SYS driver is included in the 2325 Developer’s
Toolkit. For information about purchasing the toolkit, contact
your LXE representative.
The XFER.EXE program has limited ability to access the 4-Slot Dock
network when the 4SLOT.SYS driver is not loaded. This allows you to
use the 4-Slot Dock network to download the 4-Slot Dock device driver
to any 2325 that doesn’t already have it.
You can use the Configuration Utility to transfer the 4SLOT.SYS driver
to the 2325 and modify the CONFIG.SYS file. Complete the following
steps:
1. Install the Developer's Toolkit software on your computer. (Follow
the installation instructions provided with the Developer's Toolkit.)
Be sure to include the 4-Slot Dock software during the installation
process. (You should also install the Configuration Utility at this
point, if you haven't already.)
2. Start the Configuration Utility, and select the Transfer Files button
on the main menu. Find the 4SLOT.SYS file (in the \DOS directory
if you used the default installation) and transfer it to the C:\DOS
directory on the 2325.
3. Transfer the 2325’s C:\CONFIG.SYS file to a temporary location
on your PC. Using a text editor (for example, Notepad), add the
following line to the end of the file:
device=c:\dos\4slot.sys
Save the file, and transfer it back to the c:\ directory on the 2325.
4. Reboot the 2325.
Note: You can save the file list or create a new .CFG file to transfer
the 4-Slot Dock driver and modified CONFIG.SYS file to
multiple 2325s.
