MFJ-1278B MULTI-MODE OPERATIONAL COMMANDS
Parameters:
ON <NULL> characters are sent to the terminal following <LF> characters.
OFF <NULL> characters are not sent to the terminal following <LF> characters.
This command causes transmission of <NULL> characters (ASCII code $00), producing an
effective delay following any <LF> sent to the terminal. The number of <NULL> characters
is determined by the command NULLS. This delay is required by some display terminals.
You need to set NULF ON if your terminal sometimes misses characters at the beginning of
the line.
NULLS n Mode: Packet Default: 0
Parameters:
n 0 - 30, specifying the number of <NULL> characters to send after <CR> or <LF>.
This command specifies the number of <NULL> characters (ASCII code $00) to send to the
terminal after a <CR> or <LF> is sent. In addition to setting this parameter value, NUCR
and/or NULF must be set to indicate whether nulls are to be sent after <CR>, <LF>, or both.
Devices requiring nulls after <CR> are typically hard-copy devices requiring time for
carriage movement. Devices requiring nulls after <LF> are typically CRTs which scroll
slowly. Extra null characters are sent only in Converse and Command Modes.
OK Mode: ASA Immediate Command
OK is an immediate command used in conjunction with the ASA commmand.
When the results are displayed using the ASA mode, the user can issue the OK command to
accept the results analyzed by ASA.
Typing OK will cause the MFJ-1278B to select the operational mode and match the speed
automatically against the signal being analyzed.
