Framing errors is a count from 0-99. This count shows how many times there
has been a receive error, caused by a character corruption or incorrect set-up.
Overrun errors is a count from 0-99. This count shows how many times
characters have been lost due to data being sent too quickly for the SDM-SIO4
to process the data.

First Command Option — Reset Error Counters
When command 1026 is specified in parameter 4 of Instruction 113, this
additional option can be used (parameter 5 of Instruction 113) to force the error
counters to be reset to zero.
This means that command 1026 requests data from the SDM-SIO4 and can also
be used to send these reset commands to the SDM-SIO4.
The command to reset the error counters has no effect on a port if
the command line is active.
