defined as follows:
Figure 3.4
PCLTA-20 Generic Controls
System Image Path
Specifies the full directory path for the PCLTA-20 system images. This path is set by
the PCLTA-20 Installation Software but may be modified by the user.
Layer2 and Layer6 Buffering
Controls the number of 4Kbyte operating system pages that are allocated for message
buffering within the driver. The
Layer2
setting is used by the PCLTA-20 protocol
analyzer only and should not be modified from the default of 20 pages. The
Layer6
setting is used for all other system images. The default setting of Layer6 Buffering is 6
pages. This value should be appropriate for most applications; embedded systems may
need to change the number of buffering pages.
