MFJ-1278B MULTI-MODE OPERATIONAL COMMANDS
RXERRORS:
Increments each time a received frame is thrown out due to it being too short, suffering
overrun(s), or it having a bad CRC. Latter occurs only when CRC checking is enabled (i.e.
HGARBAGE is OFF). This counter will often increment in the presence of noise.
RXLENERR:
RXLENERR counts the number of too-short frames received. The counts are of diagnostic
use only and here again, non- zero counts are not a matter of concern.
RXRESYNC:
RXRESYNC is a diagnostic health counter recording the number of receiver re-
synchronizations handled internally to the MFJ-1278B. Non-zero counts indicate the
attached radio may be either turned off or squelched. Note that in almost every situation your
radio must to have its squelch fully opened!
SENTFRMR:
Increments each time a Frame reject frame is transmitted.
SENTIFRA:
Increases by one each time an I frame is sent.
SENTREJ:
Whenever a REJect frame is transmitted, this counter is incremented.
SENTRNR:
This health counter tracks the number of times your MFJ-1278B has had to send Receiver-
Not-Ready (RNR) frames. Non-zero counts may be an indication that the RS-232 terminal or
baud rate is too slow.
TXCOUNT:
Incremented whenever a frame is correctly transmitted.
TXQOVFLW:
Counts how many times frames were disconnected because the outgoing frame queue was too
small.
TXTMO:
