Epson Multi-mode Data Controller MFJ-1278B - Manual (Page 184)

MFJ-1278B MULTI-MODE OPERATIONAL COMMANDS
AUTOTRAC ON/OFF Mode: CW Default:ON
Parameters:
ON
Allows automatic speed tracking of incoming CW signals.
OFF
Automatic speed tracking of incoming CW signals is disabled.
When AUTOTRAC is set ON, the MFJ-1278B attempts to continually track the speed of all
incoming CW signals as the speed changes, of a station that is being received.
When the last reception speed greatly differs from the speed being received now, the MFJ-
1278B will automatically initiate a LOCK, just as if you had requested one with "Control-U".
If CWSPEEDMatch is on when this automatic locking takes place, then the newly locked
speed also becomes your new transmit speed.
Small received speed changes do not cause your transmit speed to change, AUTOTRAC to
try and re-establish a speed lock to the incoming CW signal.
The AUTOTRAC feature is useful for listening while roaming the bands or for net
operation.
AWLEN n
Mode: All Default: 8
Parameters:
n 7 - 8, specifying the number of data bits per word.
This value defines the word length used by the serial IO terminal port.
For most packet operations, including conversation, bulletin board operation, and
transmission of ASCII files, you should set AWLEN 7. If 8 bit words are transmitted to the
MFJ-1278B in Command Mode or Converse Mode, the eighth bit is normally removed,
leaving a standard ASCII character, regardless of the setting of AWLEN.
To transmit and receive packets retaining all 8 data bits of each character, as you need to do
if you send executable files or other special data, you should use Transparent Mode and set
AWLEN 8. Alternatively, you can use Converse Mode and set AWLEN 8 and 8BITCONV
ON (however, the data you then send must handle the Converse Mode special characters with
the PASS prefix).
If the AWLEN command is changed, then the user must perform a RESTART on the MFJ-
