BLOCKI[NG] { ON | OFF }
BLOCKING ON specifies block mode with 2780 or 3780 blocking. You select
the type of blocking, 2780 or 3780, as a parameter in the CONNECT command.
BLOCKING ON requires that BLOCKSIZE also be specified. Otherwise, an
error occurs when you issue a CONNECT command.
If you do not specify BLOCKING, the default is BLOCKING OFF.
Specify BLOCKING OFF (or accept the default) and specify BLOCKSIZE for
block mode without blocking.
Specify BLOCKING OFF (or accept the default) and do not specify
BLOCKSIZE for standard 2780 or 3780 emulation.
BLOCKS[IZE] size
specifies the size of the text portion of a transmission block. The text portion
of a transmission block includes all characters (except the control characters
that start and end a transmission block). A normal text block is two characters
longer than the size specified here. (The actual size of a normal text block is
the size of the text portion plus one for the STX that begins the block and one
for the ETB or ETX that ends the block.) A transparent text block is three
characters longer than the size specified here.
size
can be from 2 through 4084 bytes, which results in normal text blocks
ranging from 4 through 4086 bytes.
If you omit this parameter:
2780-emulation mode sends and receives blocks up to 400 bytes long.
3780-emulation mode sends blocks up to 512 bytes long and receives
blocks up to 520 bytes long.
Operation in block mode is not possible.
C[PUS] { primary | ( primary [, backup ]) | (, backup )}
specifies the CPU in which the primary Exchange/RJE line server process is to
run ( primary ) and the CPU in which the backup line server process is to run
( backup ). Both primary and backup must be from 0 through the number of
CPUs in your system less one. For example, if your system has six CPUs, both
primary and backup must be a number from 0 through 5.
If you do not specify a CPU for the primary process, it runs in the same CPU
as the Exchange/RJE command interpreter. If NONSTOP ON has been
specified and you do not specify a CPU for the backup process, it runs in CPU
number primary +1. If this number is greater than the number of CPUs in
your system, the backup process runs in CPU 0.
