Chapter 7 - Commands and Messages

58

MARk

n

default 1600

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

MAXframe

n

default 1/4

n

 may be set to any value between 1 and 7. MAXframe sets an upper limit on the number of

unacknowledged frames which can be outstanding at any one time.

MAXUsers

n

 (0–26)

default 10/10

This command sets the maximum number of simultaneous connections allowed with this unit.

It determines the maximum number of "streams" allowed to be active at a given time (see also the

USers

  command).  When  setting 

MAXUsers

,  each  user  is  allocated  about  125  bytes  of  memory,

thereby decreasing memory available for other uses. It, is best, from an operational viewpoint, to
set  this  command  to  the  lowest  number  required  for  the  multiple  connections  you  plan  to  use.
Changing  the 

MAXUsers

  parameter  will  cause  a  system  reset.  Setting  one  or  the  other  (but  not

both) 

MAXUsers

 parameter to zero forces the KAM to do HF or VHF operations only.

MBeacon

 ON|OFF

default ON/ON

This command determines whether packets addressed to Beacon or ID will be monitored and

displayed on the screen. If you do not wish to monitor Beacon or ID packets, turn this command
OFF.

MCOM

 ON|OFF

default OFF/OFF

When ON, connect request <C>, disconnect request <D> disconnected mode <DM>, and un-

numbered  acknowledge  <UA>  packets  will  be  displayed  if  the  Monitor  command  is  ON.  Unnum-
bered information frames <UI> and numbered information frames <In> are also displayed.  The
send sequence number N(S) is d L splayed with the I-frame.

MCon

ON|OFF

default OFF/OFF

When ON, the KAM will observe the Monitor command while connected to other units. If you

want  all  packets  heard  to  be  displayed  while  you  are  not  connected,  but  wish  such  display  sup-
pressed when you are connected, leave this command at OFF.

MHClear

This command erases the stations heard log.

MHeard

This command causes display of a list of stations heard. An asterisk * indicates the station was

heard through a digipeater. A maximum of 18 stations can be logged. The time the station was last
heard is also displayed.

Monitor

 ON|OFF

default OFF/OFF

When ON the monitor function is enabled. If the unit is not in Transparent Mode, packets not

addressed to this unit may be displayed. The addresses in the packet, are displayed along with the
data portion of the packet, e.g.:

N0APJ>WA5RGU-1:Good afternoon,what time is the meeting?

Callsigns are separated by a ">" and the callsign extension field is displayed if it is other than

0. The 

MAll

 command determines whether both connected and unconnected packets will be moni-

tored.  The 

MCon

  command  determines  whether  packets  will  be  monitored  while  the  unit  is  con-

nected to other stations. All monitor functions are disabled in the Transparent Mode.

MResp

 ON|OFF

default OFF/OFF

When 

MCOM

 and 

MResp

 are both ON, monitored response packets are displayed. The received

sequence number N(R) is also displayed.  I-frames are shown with both N(S) and N(R).
