SECTION 12.

PROGRAM CONTROL

INSTRUCTIONS

which

the

alarm call is

initiated. The

randomized

retry

time

is

divided

by

the execution interual

to

determine how many

times

Instruction 97 must

be

executed before

it

calls

again.

The

Instruction

must

be

executed each time the

table

is.

Parameter

2

specifies

which

user

flag

(1-8)

is

to

be used as

the

interrupt disable

flag.

lf

this flag

is

set,

lnstruction

97

will

not initiate an alarm

call.

lf

the CR10 is

in

the

process

of

trying to

get through with an alarm call, setting the

interrupt disable flag will abort further attempts.

Instruction 97 sets this flag when an alarm call

has received the

correct

response. Instruction

97

does

not

clear this flag; the flag

will

remain

set until cleared

by

the

program or external

command.

When the

flag

is

cleared,

Instruction

97 is reinitialized.

The

RF path and/or

telephone

number

is

entered

by

following

Instruction

97

with one

or

more entries

of

lnstruction 63.

The

RF station

lDs and phone numbers are

entered

1

digit at

a

time.

Decimal equivalents of certain ASCII

characters (Appendix

E)

are used

to

identify

breaks.

Separate RF stations with

a

space

(32).

Indicate

the

switch

from

RF stations

to

a

telephone number (DC112)

with

a space

(32)

followed

by

a

"T"

(84).

Caniage

Return (13)

is

used

to

end

the

series of numbers.

lf

the call

is

to

go through

a

RF

link

to a phone,

then

the

RF Modem

is

specified

in

Parameter

1.

See

the

PC208

and

RF

manualfor

additional

interfacing notes.

When

the

DC112 Modem (Hayes compatible

commands) is specified, the following

commands are sent to

the

modem before

the

phone

number:

ATVO,

ATST=180, and ATDT.

The first command causes

the

Modem

to

respond with

digits

rather than

words.

The

second command causes

the

modem to wait

for

the

carrier

180

seconds after calling or

answering.

The third command causes

the

Modem

to

dial

the

number that follows

the

command in "Touch

Tones".

Additional

commands

can

be entered as part

of

the

telephone

number (e.9.,

","

for delay or

"P"

for

pulse

dialing).

The

CR10

will

not accept

the

line

feed

found

in some Hayes "compatible"

modems.

SEND

CHARACTER

***

lnstruction 98 is used

with

lnstruction 63 to

a

character or string

of

characters

(up

to

15)

to

the

printer.

The

printer may be either a

addressed or pin-enabled (Section 6.2).

lnstruction

63

must immediately follow

98.

The

character or characters

to

send are

entered

in

Instruction 63 as

the

decimal equivalents (99

is

the

maximum number allowed)

of

the

7

bit

ASCllcharacter

(sent as

8

bits, no

parity).

For

example,

to

send the ASCII character

control

R,

18

would

be

entered.

Enter

a

null

(0)

to

terminate the

string.

Appendix

E

contains a

listing

of

the ASCII characters.

lf the

9

pin connector is already active when

lnstruction

98

is

executed,

the

output request

is

put in

a

queue (see Instruction

96).

This

instruction

can

be used to send a control

character to activate

some

listing

device.

The

specified character(s)

is sent

at

the time

Instruction 98 and 63 are executed.
