PUP Commands
When a load system procedure finishes, the Exchange/RJE lines should be up (in the
online condition). If the lines are not up, use the PUP command to check the status of
the lines and, if necessary, place them online. For example, use the PUP command to
check the status of the bisynchronous line:
:PUP LISTDEV $BSC2
If the line has been placed offline by the system manager (and has been determined to
be operational), use the PUP command to place it online, as shown below:
:PUP UP $BSC2
CP6100 Lines This subsection describes the system generation definitions required when using
Exchange/RJE with CP6100 data communications lines. CP6100 is the
communications process that is used with the 6100 Communications Subsystem (6100
CSS). For more complete information on how to define 6100 CSS and CP6100 data
communications lines, see the System Generation Manual.
When configuring CP6100 line for Exchange/RJE, you need to specify the following
values. Note that this is not a complete list; it only includes those parameters for
which Exchange/RJE requires a specific value.
Peripherals Paragraph Macro Name
BISYNC
Binary Synchronous Communications (BSC; also called bisynchronous) protocol,
required for Exchange/RJE data communications lines.
CP6100 Communications Process Modifiers
AUTOCONF
specifies that the CP6100 process sends the current configuration block to the LIU
on the first open after a download. AUTOCONF, which is the default value for
BISYNC, is required for Exchange/RJE.
Data Communications Line (BISYNC Macro) Modifiers
BSCASCII or none
specifies that the control characters are ASCII control characters. By default, the
control characters are assumed to be EBCDIC control characters. The selection of
ASCII or EBCDIC defines the line as either an ASCII line or an EBCDIC line.
However, this selection does not restrict the character codes of the data
transmitted over the line. For example, you can transmit ASCII data over an
EBCDIC line. This selection does determine which code is used for the BSC line-
control characters, which in turn determines the codes the hardware recognizes as
line-control characters. This selection must agree with the line code used on the
remote system.
