-P
n Check Parity
-P0
Ignores parity of special characters.
-P1
Processes special characters only if their parity matches that of the serial port.
-P2
Processes special characters only if their parity matches that of the serial port.
Recognizes modem port flow-control characters, however, regardless of whether their
parity matches the serial port parity.
Controls checking of parity for XON and XOFF characters, the escape code sequence,
and HP ACK characters. In command state, the modem sends all command echoes and
command responses to the computer with parity that matches the serial port’s.
When -P0 or -P1 is set, all received data is passed through to the computer at 8 data
bits, no parity.
When -P2 is set, all received data is passed through to the computer with parity
corrected to match the serial port parity.
NOTE
The -P command is used only for 10-bit data; the modem ignores -Pn when it is
set for 11-bit data.
