MFJ-1270C/1274C MANUAL COMMANDS
Page 117
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 TNC 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 TNC. If not, the command will remain unchanged.
A
X25L2V2 ON|OFF Mode: Packet Default: ON
Parameters:
ON The MFJ TNC will use AX.25 Level 2 Version 2.0
protocol.
OFF The MFJ TNC will use AX.25 Level 2 Version 1.0 protocol.
Some implementations of the earlier version of AX.25 protocol (e.g., TAPR's
TNC 1) won't properly digipeat version 2.0 AX.25 packets. This command exists
to provide compatibility with these other TNCs until their software has been
updated.
During the protocol transition period, you should set
AX25L2V2 OFF .
After your local area TNCs are updated to the newer protocol version, you should
set
AX25L2V2 ON .
