SET LS
(LS)
Sets the serial-printer handler.
Format
SET LS condition
Condition
[NO]BIT8
BIT8 sets the LS handler to pass the eighth bit unaltered, but does not guarantee
the eighth bit will arrive at the output device unaltered. The following can alter
or strip the eighth bit:
• Some RT–11 utilities in ASCII mode
• Some RT–11 KMON commands, such as PRINT
• Hardware device initialization program options
• Hardware device straps
NOBIT8, the default, sets the LP handler to force the eighth bit to zero, but does
not guarantee the eighth bit will arrive at the output device as zero.
[NO]CR
CR, the default, sends carriage return characters to the line printer. To allow
overstriking on the printer, use this condition for any FORTRAN program that
uses formatted input and output. (Use CR also for any LS11 or LP05 line printer
to prevent loss of the last line in the buffer.)
NOCR prevents RT–11 from sending carriage returns to the printer. This setting
may produce a significant increase in printing speed on some line printers, where
the printer controller causes a line feed to perform the functions of
RETURN
.
CSR=n
Modifies the line printer handler to use n as the Control and Status Register
(CSR) address for the printer controller. The valid range for n is 160000 to
177570
8
. This option enables you to set a special CSR value in the printer handler
itself, without having to modify the handler source code and reassemble. Use this
option if you have installed the printer controller at a nonstandard address.
[NO]CTRL
CTRL, the default, passes all characters, including nonprinting control
characters, to the printer. Use this condition to pass the bell character to the
LA180 printing terminal.
NOCTRL ignores nonprinting control characters.
