MFJ-1270C/1274C MANUAL COMMANDS
Page 143
RCVDREJ : Increases for each reception of an REJect frame from
a connectee.
RCVDRNR : Counts the number of AX.25 L2 receiver- not-ready
frames received since power-up and during
connections. The count may be useful in gauging
system throughput.
RCVDSABM : Each received SABM frame addressed to the MFJ
TNC causes this counter to be increased by one.
RXABORT : RXABORT is a count of the number of hardware-
detected HDLC abort events. A large number of
counts is perfectly normal and should not cause
concern.
RXCOUNT : Increases when any frame is received with good CRC
(or any CRC if HGARBAGE is turned on).
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 resynchronizations handled
internally to the MFJ TNC. 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.
