Reference: Remote Commands ~ Command Description

:SENSe:DATA:SPE:STUFfing

This command controls the receiver’s treatment of columns 30 and 59, which can be used for SPE fixed byte stuffing. When enabled, these columns are treated as stuffing columns and are not considered part of the payload. When disabled, columns 30 and 59 are treated as part of the payload. This command is applicable only to STS-1 structure. The query form returns the current setting.
