ptem - Null STREAMS module for pseudoterminal emulation
DESCRIPTION
The ptem module is a null STREAMS module that Tru64 UNIX provides to applications for use in place of the AT&T System V Release 4 ptem mod-
ule. The AT&T System V Release 4 ptem module emulates a pseudoterminal when used in conjunction with a line discipline and a pty device
driver. In Tru64 UNIX, all of the AT&T ptem functions are included in the pty slave device driver.
The client process pushes the null ptem module onto the slave side of the pty device stream below the ldterm module by a call to the
STREAMS I_PUSH ioctl() function.

pckt - STREAMS module for constructing message packets on a pty
DESCRIPTION
The pckt module is a STREAMS module that can be used with a pseudoterminal to transfer messages in packet mode. The packet mode feature of
pty devices allows the user process on the master side of the device to be informed of state changes.
For packet mode to be enabled in the pty device, the user process must push the pckt module onto the master side of the pty with a call to
the STREAMS I_PUSH ioctl() function.
When the user process writes data, the pckt module passes the message on to the next module or driver unchanged. When the user process
reads data or when the pckt module receives certain STREAMS message types, it constructs a packet out of the message for forwarding
upstream.
To construct a message packet, the module creates an M_PROTO message. This M_PROTO message contains the original message type in the first
data block and the original message in as many data blocks as needed. The user process can then retrieve the M_PROTO message with a call
to the getmsg() function.
The STREAMS message types that the pckt module places in packets, are the following: M_DATA M_IOCTL M_PROTO M_PCPROTO
M_FLUSH M_START M_STOP M_STARTI M_STOPI M_READ
All other messages are passed unchanged upstream.
If the message is an M_FLUSH message, the pckt module looks at the flag and takes the following actions: If the flag is FLUSHW, the module
changes it to FLUSHR before creating the M_PROTO message, and passes the message upstream. The module also sends an M_FLUSH message with
the FLUSHW flag set. If the flag is FLUSHR, the module changes it to FLUSHW before creating the M_PROTO message, and passes the message
upstream. If the flag is FLUSHRW, the module changes it to FLUSHW before creating the M_PROTO message, and passes the message upstream.
The module also sends an M_FLUSH message with the FLUSHW flag set.
