The 4SLOT.SYS Device Driver
To use terminal-demand mode within a custom application or to use host-
controlled mode, the
4slot.sys
DOS device driver should be 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.
The
xfer.exe
program has limited ability to access the Falcon 4-Slot Dock
network when the
4slot.sys
driver is not loaded. This allows use of the
Falcon 4-Slot Dock network to download the Falcon 4-Slot Dock device driver
to any portable that doesn’t already have it.
The Falcon Configuration Utility can transfer the
4slot.sys
driver to the
portable and modify the
config.sys
file. Complete the following steps:
1.
Install the Developer's Toolkit software on the computer. (Follow the
installation instructions provided with the Developer's Toolkit.) Be sure
to include the 4-Slot Dock software during the installation process.
(Install the Falcon Configuration Utility at this point, if not already
installed.)
2.
Start the Falcon Configuration Utility, and select the
Transfer Files
button on the main menu. Find the
4slot.sys
file (in the
percon\falcon\dos
directory if the default installation was used)
and transfer it to the
c:\dos
directory on the Falcon unit.
3.
Transfer the Falcon’s
c:\config.sys
file to a temporary location on
the PC. Using a text editor (for example, Notepad), add the following
line to the end of the file:
4.
Save the file, and transfer it back to the
c:\
directory on the Falcon.
5.
Reboot the Falcon.
The
4slot.sys
driver is included in the Falcon Developer’s Toolkit. For information
about purchasing the toolkit, contact a PSC representative.
