X.25 Status 165

X.25 Call user data

Call user data can be used to request services specific

to the host you are calling, such as a password, or to indicate your Protocol ID

code. The call user data field can contain up to 10 bytes. The display shows

both a “dump” format (see left-hand column) and the ASCII equivalent (see

right-hand column).

Trace

Indicates whether this protocol is currently being traced using

ECMODULE TRACE.

Trace buffer size (bytes)

The size of the trace buffer.

Trace filter (hex)

The trace filter lets you tailor the trace to examine certain

groups of elements within the data stream. The trace filter is one byte long,

with each bit filtering a specific type of protocol element. When you filter an

element, you hide everything but that element. The trace filter is specified as a

two-digit hexadecimal number. For more information, see “Trace Filter” on

page 172.

Trace entry size (bytes)

This configures Trace to examine only the first

n bytes of each frame or packet traced. If you have a Trace Entry Size of 32

bytes, only the first 32 bytes of each frame or packet is loaded into the trace

buffer.
