read stuffing

This action can be executed on responses only.

Sometimes, in the data block of a command, it is not allowed to use certain symbols because they are being used as control bytes in that same command.

In that case, if you do want to use one of those symbols, it has to be preceded by a redundant character to indicate that it should not be processed as a control byte but as data. This adding of redundant characters is also known as stuffing.

The “read stuffing” action allows you to remove those redundant characters when a response is received.
