FUNCTIONAL MODES
1.8.1 TRANSFER TO
COMPUTER/PRINTER
This section describes
commands
1
and
2
(Table
1.8-1). TERM (PC208 Software)
automaticaily uses
these commands for
uploading and downloading programs.
SENDING
ASCII PROGRAM INFORMATION
Command
1 is
to send
the program listing
in
ASC|l.
At the end of
the listing, the 21X sends
control
E
(5 hex or decimal)
twice.
Except when
in
telecommunications,
the baud
rate
code must
be entered after
command
1.
Table 1.8-4 is an example
of
the program listing
sent
in response to command
1
(the actual
listing is
in
one column but
is
printed
in
two
columns to save
space).
Note that
the listing
uses numbers
for each
mode: The
numbers
for
*A,
*8,
and
*C modes are 10,
1
1
,
and
12,
respectively.

LOAD PROGRAM FROM
ASCII
FILE
Command 2 sets
up
the 21X to load a serial
ASCII program. The format
is
the same as sent
in response to command
1
(Table 1.8.4).
Excepl
when
in
telecommunications,
the baud
rate
code must
be
entered after command
2.
A download
file need
not
follow exactly the
same format
that is used when listing
a
(i.e., some
of
the characters sent
in
the listing
are not really used when a program is loaded).
Some rules which must
be
followed
are:
"M" must
be
the first character other
than
a
carriage return (CR) or line feed
(LF).
The
"M" serves the same function
as "*" does
from
the keyboard. The order that the
Modes are sent in
does not matter (i.e., the
information
for Mode
4
could be sent before
that
for Mode
1).
"S" is necessary prior to the execution
interval (Scan
rate).
The
colons (:) are used to mark the start of
actualdata.
