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.
