Statistic
Meaning
Character Driver Statistics
Rx total
Total number of characters received
Rx errors
Number of hardware receive errors (UART overrun
or framing error). If the ratio of Rx errors to Rx total
is worse than 1 in 10,000, consider reducing your
baud rate.
Rx buffer overruns
The number of times the receive buffer could not
accept additional data. Indicates a cabling problem
or modem not responding to hardware flow control.
Rx flow off
The number of times that hardware flow control was
used to throttle receive data from the modem.
Tx total
Total number of characters transmitted
Packet Statistics
Total packets sent
Total number of packets sent.
Total packets received
Total number of packets received.
Checksum errors
The number of packets with invalid checksum,
indicating a data error.
Send packet too small
The number of send packets smaller than the
minimum size.
Send packet too big
The number of send packets larger than the
maximum size.
No ECB available
The number of packets received for which no
application was listening. (This is not necessarily an
error condition.)
Receive packet overflow
The number of packets received for which no
internal buffer is available.
Receive packet too big
The number of received packets larger than the
maximum size.
Receive packet too small
The number of received packets smaller than the
minimum size.
Send packet miscellaneous
The number of send packets with hardware errors.
Receive packet miscellaneous
The number of receive packets with hardware errors.
Received mismatches
The number of packets with invalid media headers.
(This should never happen.)
