Epson Multi-mode Data Controller MFJ-1278B - Manual (Page 222)

MFJ-1278B MULTI-MODE OPERATIONAL COMMANDS
ESCAPE ON/OFF Mode: Packet Default: OFF
Parameters:
ON
The <ESCAPE> character ($1B) is output as "$" ($24).
OFF
The <ESCAPE> character is output as <ESCAPE> ($1B).
This command specifies the character which will be output when an <ESCAPE> character is
to be sent to the terminal. The <ESCAPE> translation is disabled in Transparent Mode.
This command is provided because some terminals, and computer programs that emulate
such terminals, interpret the <ESCAPE> character as a special command prefix. Such
terminals may alter their displays depending on the characters following the <ESCAPE>. If
you have such a terminal, you can protect yourself from unexpected text sequences and from
other packeteers by setting ESCAPE ON.
See also the MFILTER command, which allows general character stripping (rather than
character translation) in monitored packets.
EXActcal ON/OFF
Mode: Pactor Default:ON
Parameeters:
ON
Enables exact callsign matching with connect packets
OFF
Disables exact callsign matching with connect packets.
When the EXActcal command is ON, the MFJ-1278B responds to connect packets that match
all the letters in your callsign and no more. When OFF, the looser "buggy" Pactor
specification comes into play and your MFJ-1278B responds to any connect packet containing
at a minimum the contents of MYCALL. EXACTCAL matching will not always work to filter
out improper callsigns when the offending unit is the pacomm Pactor version 1.0 unit because
of its use of regular ascii 0x55 ("U") characters to fill and terminate callsigns. MFJ uses ascii
0x0f as specified in Pactor documents, instead of 0x55 to fill, and thus fixes the bug.
