Chapter 7 - Commands and Messages

63

SCreenl

n

default 80

This value is used to properly format terminal output. A CR sequence is sent to the terminal at

the end of a line when n characters have been printed. A value of zero inhibits this action.

n

is var-

iable from 0 to 255.

SEndpac

n

default $0D (CR)

n

may be set to any value between 0 and $7F, or, if

8bitconv

is set to ON, may be set to any

value between 0 and $FF, specifying a character that will force a packet to be sent in Convers
Mode.

SHift

n

default 170

This command sets the default shift used in non-CW modes. Shifts available are 170, 425, 850

or modem. When modem is specified, the

MARk

and

SPace

commands set the mark and space fre-

quencies used. The modem tones are always selected for Packet operation. Once you have en-
tered a non-Packet mode, CTRL-C S can be used to change shifts without affecting the

SHift

pa-

rameter.

SLottime

n

default $0D (CR)

n

can be any value from 0 to 255 specifying the amount of time in tens of milliseconds be-

tween successive tries of the persistence algorithm.

SPace

n

default 1800

This command sets the space frequency used when the unit is in the modem shift.

STARt

n

default $11 (CTRL-Q)

This command selects the character used to restart output from the unit to the terminal. Out-

put is stopped with the

STOp

character.

STATShrt

ON|OFF

default OFF

If ON, entry of the Status command will display only the current I/O stream and other streams

having a connected status.

Status

This is an immediate command which will display both the identifier and link state of all

streams. The current input and output stream is also indicated. A pound sign (#) indicates that
there is unacknowledged data in the buffers for that stream. The following is an example of a dis-
play which may result from entry of the

Status

command:

cmd:

Stat

A Stream

I/O CONNECTED TO W0XI

B STREAM

CONNECTED TO N0APJ

C STREAM

DISCONNECTED

........
........
I STREAM

CONNECTED TO NQAL VIA LAW 3

J STREAM

#CONNECTED TO KE0H

........
Z STREAM

DISCONNECTED

STOp

n

default $13 (CTRL-S)

This command selects the character used to stop output from the unit to the terminal. Output

is restarted with the

STARt

character.
