4.3.1.4 Physical vs. Logical Byte Display
The
Event Display
window and
Event Pane
in the
Frame Display
window show the . In other words,
they show the actual data as it appeared on the circuit. The Radix, Binary and Character panes in the Frame
Display window show the , or the resulting byte values after escape codes or other character altering codes
have been applied (a process called ).
As an example, bytes with a value of less than 0x20 (the 0x indicates a hexadecimal value) cannot be
transmitted in Async PPP. To get around this, a 0x7d is transmitted before the byte. The 0x7d says to take the
next byte and subtract 0x20 to obtain the true value. In this situation, the Event pane displays 0x7d 0x23,
while the Radix pane displays 0x03.
4.3.1.5 Sorting Frames
By default, frames are sorted in ascending numerical sequence by frame number. Click on a column header
in the
Summary
pane to sort the frames by that column. For example, to sort the frames by size, click on the
Frame Size
column header.
An embossed triangle next to the header name indicates which column the frames are sorted by. The
direction of the triangle indicates whether the frames are in ascending or descending order, with up being
ascending.
Note that it may take some time to sort large numbers of frames.
4.3.1.6 Frame Display - Find
Frame Display
has a simple
Find
function that you can use to search the Decode Pane for any alpha
numeric value. This functionality is in addition to the more robust
Frame Display Find
