Even The port expects to receive data frames with an even number of
logical 1's per byte. The port transmits XOFF and XON with even
parity. If the port detects a parity error, the port sends an
inverted question mark to the printer instead of the character
sent by the host system.
Odd The port expects to receive data frames with an odd number of
logical 1's per byte. The printer transmits XOFF and XON with
odd parity. If the printer detects a parity error, the port sends
X'5F' to the printer instead of the character sent by the host
system.
None The port expects no parity bit when it receives data. The port
transmits XON and XOFF without parity bits.
Ignore The port expects a parity bit when the port receives a data frame.
The port ignores the parity bit. The port uses even parity when it
transmits XON and XOFF.
