About the port statistics displayed by "info serial"
The statistics displayed by "info serial" include data, event, and error
counts, described below. These statistics are useful in understanding how
the device is operating and can be helpful in finding problems. In particular,
if an error counter is found to be increasing, there may be a problem in the
device. The numbers on these statistics will only increase from their
previous counts, unless you set the count back to zero by issuing an
info clear command.
Examples Display the IP table
#> info ip

#> info ia:modbus

#> info sou:1

See also The "info" command displays statistical information about a device over
time. In contrast, the "display" command’s focus is on real-time information,
while the "status" command displays the status of outgoing connections
(connections made by "connect," "rlogin," or "telnet" commands). For more
information, see these commands:
• "display" on page 59.
• "status" on page 254
