Mode Setting Commands (continued)
________________________________________________________
Command
Function
________________________________________________________
n = 1, tells the remote Model 3022 to enter Remote
Online Command Mode. The following statements
apply:
• If this command was entered on local sub-channel
1, then it will request sub-channel 1 of the remote
Model 3022 to enter Remote Online Command
mode. Sub-channel 2 will remain in Online Data
Mode.
• After this command is entered, only AT commands
followed by @ will be sent to the remote Model 3022.
H
Hangup/disconnect command. Enter when the local Model
3022 is in Local Online Command Mode. Upon receiving
this command, the local Model 3022 will drop DTR at the
composite port for approximately 250 msec, and return to
Local Offline Command Mode.
Jn
Selects XON character “n”, where “n” is a single ASCII
character, either a control character or an upper or lower
case alpha character (A through Z, or a through z). NULL,
ETX, STX and Carriage Return characters are not allowed.
Kn
Sets the "no activity kill timer" (times out of Local Offline
Command Mode or PassThru Mode and enters Online
Data Mode if no activity is detected) in one quarter minute
increments. Valid values are 0 thru 15. K8 is the default,
resulting an a 2 minute command mode time out. The
timer starts running when the "T" key of the "AT" command
is pressed. Note: this time limit should not be set too
short, or time outs will occur during the entry of AT
commands.
n = 0, disabled
n = 1, 1/4 minute
n = 2, 1/2 minute
n = 3, 3/4 minute
n = 4, 1 minute
n = 5, 75 seconds
n = x, x/4 minute
[Note: if K0 is selected, the local Model 3022 will stay in
Local Offline Command Mode indefinitely, until either CD of
the main channel becomes active (if this option is enabled)
or an AT[0 command is entered.]

Nn
Selects XOFF character “n”, where “n” is a single ASCII
character, either a control character or an upper or lower
case alpha character (A through Z, or a through z). NULL,
ETX, STX and Carriage Return characters are not allowed.
O
Return to online data mode. If you have enabled
multiplexer operation, the Model 3022 waits for a
connection to the remote Model 3022. You only issue this
to the local Model 3022.
Rn
Enables or disables remote control of the Model 3022.
*n = 0, remote control disabled
n = 1, remote control enabled
T
Causes a software reset with all Model 3022 modes and
channel configurations set to
factory default values. The
Model 3022 will then enter offline command mode.
(Note: The user must wait approximately 5 seconds after
receiving the “OK” response before entering new
commands.)
Un
Packet size selection. This configuration is applied to the
composite channel to determine the size (in data bytes) of
the data packet being transmitted to the modem.
n = 0, 8 bytes
*n = 1, 16 bytes
n = 2, 24 bytes
n = 3, 32 bytes
n = 4, 48 bytes
n = 5, 64 bytes
n = 6, 96 bytes
n = 7, 128 bytes
Vn
View channel configuration or mode configuration
n = 0, view the configuration of the composite channel
n = 1, view the configuration of sub-channel 1
n = 2, view the configuration of sub-channel 2
n = 3, view the configuration of the composite channel
