Optional Parameters
Example
XXX PAD
The packet assembler disassembler is a device that collects data from a group of
terminals and outputs the data in packets (data organized in a special format). It can
also take the data packets from a host and turn them into a character stream that can
be transmitted to the terminals. The XXX PAD is defined by the following values:
zX.3—Specifies the parameter for terminal handling functions such as baud rate,
flow control, character echoing, and other functions for a connection to an X.25
host.
zX.28—Specifies the user interface for locally controlling a PAD.
Note: The communication server is not a PAD.
zX.29—Specifies a protocol for setting the X.3 parameters via a network
connection.
XXX PAD calls can be made from AI296 with a PAD shell command or by defining an
alias that routes a call to the destination XXX PAD call. An XXX PAD destination is
defined like an X.25 SVC destination with the addition of XXX as the called protocol.
When XXX is used as a call protocol, it can take arguments to set the X.3 parameters,
similar to the set command used within the pad shell command.
-U Prevents the PAD protocol from passing breaks upstream.
-D Prevents the PAD protocol from passing breaks downstream.
-R Causes the PAD protocol to reply to X.25 breaks.
-7:21 Causes the X.3 parameter to behave like X.25. This option sends an
interrupt packet (an indication of a break PAD message) and discards data
to the terminal.
-M Enables Macstar compatibility.
PAD -U Provides PAD break handling, but prevents the break from being
propagated upstream.
