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 their 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 PC with parity that matches the serial port’s.
With -P0 or -P1 set, all received data pass through to the computer
at 8 data bits, no parity.
With -P2 set, all received data pass through to the computer with
parity corrected to match the serial-port parity.
NOTES 8 -bits and mark parity. The AT sequence cannot be used to
match 8-bit data with mark parity. Eight data bits plus mark
parity can only be set by the AT-O command. If -O7 is not set,
the modem defaults to 8 data bits, no parity.
Space parity. The AT sequence cannot be used to match
space parity; no parity is set instead. You must enter AT-O3 to
set space parity.
NOTE The -P command is used only for 10-bit data; the modem
ignores -Pn when it is set for 11-bit data.
