MFJ-1270C/1274C MANUAL COMMANDS
Page 142
ASYFRERR : This is a health counter reflecting the number of
hardware-detected asynchronous framing errors.
Framing errors are not fatal. They merely indicate
that the terminal attached to your MFJ TNC is not
configured correctly with regard to
AWLEN/PARITY.
ASYQOVER : Records the number of times received- connected
packets have been rejected due to insufficient space
in the buffer holding the data going to the terminal.
No actual data loss occurs, provided the connection
remains intact. ASYQOVER counts can be avoided
by increasing the speed of the attached RS-232
terminal and/or printer. (SEE also SENTRNR)
ASYRXOVR : Increases when the software does not service the
asynchronous receiver in time. Indicates data from
the user to the MFJ TNC is being dropped. This
error counter should never become non- zero under
supported data rates.
BBFAILED : Counts number of times bbRAM checksum was in
error.
DIGISENT : Each frame digipeated by the MFJ TNC causes the
counter to increase.
HOVRERR : Increases when HDLC receiver is not serviced rapidly
enough and data is lost. This counter should never
increment at any supported data rate.
HUNDRERR : Increases when the HDLC transmitter is not serviced
rapidly enough and frames are aborted. This counter
should never be non-zero at any supported data rate.
RCVDFRMR : Increases when Frame reject frames are received from
a connected station.
RCVDIFRA : Increases for each reception of an I frame from a
connectee.
