Flags Field

The flags field of a server table mapping line contains one or more flags that may be used to control or modify the actions the server takes when processing a call request that has been mapped to that line. Flags specify options that are unique to the mapped line. A brief description of each flag is provided in Table A-1.

⎜ Flag		⎜	Description	⎜
⎜		⎜		⎜
⎜	a	⎜ Additional arguments should be read from the incoming data channel before execu-		⎜
⎜		⎜ tion of the program. This flag should be specified only for remote execution channels		⎜
⎜		⎜ (see x option).		⎜
⎜	e	⎜ Arranges for the exit code of the program to be passed back to the originating system.		⎜
⎜		⎜	This flag should be specified only for remote execution channels.	⎜
⎜	h	⎜	Invokes the mapped program with the SIGHUP hangup signal ignored.	⎜
⎜		⎜		⎜
⎜	t	⎜ Opens the tty mode data service and invokes the program with the stdin, stdout, and		⎜
⎜		⎜ stderr files attached to the /dev/dkt/?.??? device for the tty channel. Note that the t flag		⎜
⎜		⎜ should be used with caution when it is associated with non-standard service. The t		⎜
⎜		⎜ flag uses a TTY interface that echoes its input by default. Origination endpoints other		⎜
⎜		⎜ than a user terminal (from a DESTINATION prompt or a dkcu) will not receive the		⎜
⎜		⎜ echoed data. If the data is not drained by the originating endpoint the network will		⎜
⎜		⎜ flow control the echoed data which will build up on the destination host. The UNIX		⎜
⎜		⎜ System STREAMS module ldterm that actually echoes the data, does not honor flow		⎜
⎜		⎜ control and will consume all of the STREAMS resources.		⎜
⎜	u	⎜	Opens the raw [URP protocol] data service and invokes the program with the stdin,	⎜
⎜		⎜	stdout, and stderr files attached to the /dev/dk/?.??? device for the raw channel.	⎜
⎜		⎜		⎜
⎜	v	⎜ Environment variables should be read from the incoming data channel before execu-		⎜
⎜		⎜ tion of the program. This flag should be specified only for remote execution channels.		⎜
⎜	x	⎜ Opens the remote execution protocol data service and invokes the mapped program		⎜
⎜		⎜	with the stdin, stdout, and stderr files attached to the /dev/dkx/?.??? device for the	⎜
⎜		⎜	remote execution channel.	⎜
⎜	I	⎜	Creates an INIT_PROCESS type utmp entry for the invoked program. This style of	⎜
⎜		⎜		⎜
⎜		⎜	accounting makes an entry in the system utmpx file that is transparent when using the	⎜
⎜		⎜	default options of the who command. It also makes an entry in the system wtmpx file	⎜
⎜		⎜	that may be displayed using the command last.	⎜
⎜	L	⎜ Creates a LOGIN_PROCESS type utmp entry for the invoked program. This style of		⎜
⎜		⎜ accounting makes an initial entry in the system utmpx file that is transparent when		⎜
⎜		⎜ using the default options of the who command. This style of accounting assumes that		⎜
