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
