### Null Stripping

If the physical device driver is enabled for null stripping, characters read in from the receive hardware (nonerror or nonbreak) with a value of 00h are thrown away. These null characters are stripped (not checked for Automatic Transmit Flow Control), even if the XON or XOFF character has been set to 00h, and are not placed in the physical device driver receive queue.

Initial Value Null stripping is disabled.
First Level Open Null stripping is disabled.
Mode Utility No effect.
