Setting Parity in /etc/uucp/Systems File

In some situations, you have to reset the parity because the system that you are calling checks port parity and drops the line if it is wrong. The expect-send couplet, "" P_ZERO, sets the high-order bit (parity bit) to 0. See this expect-send couplet in the following example:

unix Any ACU 2400 12015551212 "" P_ZERO "" \r ogin: Puucp ssword:Passuan

The following are parity couplets that can follow the expect-send couplet, "" P_ZERO:

"" P_EVEN

Sets the parity to even, which is the default

"" P_ODD

Sets the parity to odd

"" P_ONE

Sets the parity bit to 1

These parity couplets can be inserted anywhere in the chat script. The parity couplets apply to all information in the chat script that follows "" P_ZERO, the expect-send couplet. A parity couplet can also be used in entries in the Dialers file. The following example includes the parity couplet, "" P_ONE:

unix Any ACU 2400 12015551212 "" P_ZERO "" P_ONE "" \r ogin: Puucp ssword:Passuan
