serial_parity

This variable sets the RSC serial port parity; valid values are none, odd, or even. The default setting is none. Changes to this variable take effect on the next login connection over the RSC serial port.

If you change the serial parity setting after configuring the serial port modem, you must reconfigure the modem; see "Modem Reconfiguration Required After Changing RSC Serial Port Settings".
