MFJ-1278B MULTI-MODE OPERATIONAL COMMANDS

DISPLAY is an immediate command, and with no class parameter will cause all control parameters and their current values to be displayed. Sub-groups of related parameters can be displayed by specifying the optional parameter-class. Individual parameters can be displayed by entering the parameter name with no options.

DISPLAY Mode: AMTOR Immediate Command

Used to display all of the current AMTOR parameters, type DISPLAY at the "a_cmd:" prompt. The user must be in the AMTOR mode to obtain the a_cmd: prompt.

DWAIT n Mode: Packet Default: 33

Parameters:

n0 - 250, specifying default wait time in 10 ms intervals.

This value is used to avoid collisions with digipeated packets. The MFJ-1278B will wait the default wait time after last hearing data on the channel before it begins its own keyup sequence, unless the MFJ-1278B is waiting to transmit digipeated packets. This value should be agreed on by all members of a local area when digipeaters are used in the area. The best value will be determined by experimentation, but will be a function of the keyup time (TXDELAY) of the digipeater stations.

This feature is intended to help alleviate the drastic reduction of throughput that occurs on a channel when digipeated packets suffer collisions. It is necessary because digipeated packets are not retried by the digipeater, but must be restarted by the originating station. If all stations specify a default wait time, and the right value of n is chosen, the digipeater will capture the frequency every time it has data to send, since digipeated packets are sent without this delay.

The DWAIT timer is defeated (superseded) when the command ACKPRIORITY is ON.

EAa ON/OFF Mode: Pactor Default ON

"Echo As Acknowledged". When ON the TNC echos transmitted data to the terminal upon receipt of the remote's acknowledgement of the same data.
