products by using the Windows 3.1 or Windows 3.11 operating systems with proper
Windows Card & Socket Services, or by using the Windows 95 operating system
with Microsoft-provided Card & Socket Services. The Windows 3.1x and Windows
95 PCC-10 card installation software will prompt the installer to automatically add
this version of the DOS driver. The driver is small in size, and allows a DOS
session under Windows to have access to the PCC-10 through the device driver
running as part of Windows. The driver will not function unless a Windows session
is running, and the PCC-10 device driver is installed.
The following line will be added to the CONFIG.SYS file:
DEVICE=<directory of file>\LDVVDD.SYS (/Dn or /Vxxxx)
/Dn where (n) is 1-4. This defines LON1-LON4, and corresponds to devices
1-4 as determined by the PCC-10 Card device driver under Windows.
/Vxxxx where (xxxx) describes the VxD ID, in hexadecimal. This is not required
for the PCC-10 Card device driver since the default setting will work. To
use the services of the PCLTA/PCNSI Windows 95 device driver,
ECHPCLTA.VXD, you must use /V3474 instead of /D1.
The following is an example of the line that would be added to the CONFIG.SYS
file:
DEVICE=C:\LONWORKS\BIN\LDVVDD.SYS /D1
The second version of the driver, known as the Real-Mode DOS Driver, is for use
with Microsoft DOS where no Windows operating system is being used.
Real-Mode DOS Driver
Real-Mode DOS support for the PCC-10 Card (tested on DOS 6.22) consists of a single
device driver named LDVPCC10.SYS which can control up to four (4) cards, third
party DOS-level PCMCIA Card and Socket services provided by the manufacturer of
your PCMCIA card slot, and associated files. These files consist of an INI file and the
PCC-10 Card system images.
Follow these steps to install the real-mode DOS driver:
!
To use a PC Card under DOS (without using the Windows Card
& Socket Services), the PC must have “DEVICE=” references to
DOS-level Card & Socket Services in the CONFIG.SYS file, and
appropriate card services drivers loaded on the PC.
These “DEVICE=” references to card services must precede the
references to the PCC-10 Card driver to function.
