MFJ-1278B MULTI-MODE OPERATIONAL COMMANDS

ANSWRQRA ON/OFF Mode: Packet Default: ON

Parameter:

ON MFJ-1278B responds to non-digipeated UI frames addressed to QRA, within 1 to 16 seconds, with an empty ID packet.

OFF Disables MFJ-1278B 's ping-response function.

QRA ("Who are you") pinging is supported by the MFJ-1278B. A QRA ping polls all of the TNCs within range. A random number of seconds later, each TNC that heard the QRA ping will transmit its identification packet. The purpose of this feature is to reveal to the packeteer, particularly the transient one, the names of all reachable TNCs and digipeaters.

In order to send a QRA ping:

1.Set the unprotocol callsign to QRA

cmd: UNPROTO QRA<CR>

The MFJ-1278B will respond with whatever the UNPROTO command was set to previously.

2.Manually send an unconnected packet

cmd: CONVERSE<CR> <CR>

^C

cmd:

This sequence will send an unconnected packet. Once the local TNCs have responded with ID packets, then the user can press a "CRTL-C". The MFJ-1278B will respond with the cmd: prompt.

ARCVCHAR nn Mode: RTTY/ASCII Default: $12

Parameter:

nn= 0 to 127, decimal or $00 to $7F, hexadecimal

The ARCVCHAR command specifies the character used in RTTY/ASCII/CW modes to return to the receive mode after transmitting.
