The device driver for the PCLTA-20 card and the driver for the Model 33100-00
LonManager Protocol Analyzer ISA-bus card share the same Windows VxD identifier.
As a result, both types of cards cannot run on a PC at the same time. So, the PCLTA-

SYSTEM.INI
entry that loads the ISA-
bus driver.
The LonManager Protocol Analyzer software does not run under Windows Me, Windows

unless the system image files are copied and renamed.
