has been a receive error, caused by a character corruption or incorrect set-up.

characters have been lost due to data being sent too quickly for the SDM-SIO4

to process the data.

Line break errors is a count from 0-99. This count shows how many times the

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.
