UTILITY PROGRAMS
L Toggle Line Feed Option
This command tells
TERMINAL
how to handle an incoming line feed X'OA'.
When the option is on, all line feeds are ignored. When it is off, they are not
ignored.
The option is useful if the host program always sends a line feed after a
carriage return. Since the
TRSDOS
display and printer drivers automatically
perform a line feed after a carriage return is sent, the incoming line feed is
redundant. Therefore the line feed option should normally be on.
To toggle (change the state of) the line feed option, type:
_ .... ENTER MENU SELECT I ON L
(ENTER)
The new state of the option (on or off) will be displayed, and the menu
prompt will return.
P Toggle Printer Option
This command turns the printer option on and off. When the option is on,
incoming text will be copied to the printer as it is received and displayed.
Whenever you use D command while this option is on, the
RAM
buffer text
will be copied to the printer.
Be sure you have initialized the printer with the
FORMS
command before
attempting to use it.
To toggle the printer option, type:
....- ENTEJ< I"IENIJ f.;EL..E
cr
I
ON P
(ENTER)
The new state of the option (on or off) will be displayed, and the menu
prompt will return.
TERMINAL
uses a circular buffer for efficient output to the printer. However,
if characters come in too fast, they will not be printed. They
will
be displayed,
though, and will be saved in
RAM
if the buffer is open. (Check your printer's
specifications for maximum character input rate. At 300 baud, 7-bit
characters may come in as fast as 30 per second.)
To minimize hookup time, don't use the printer option while on-line with the
host program. Save the incoming text in
RAM
instead. After completion of
the hookup, tum the printer option on and use the D command to get a hard
copy of the data.
