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 module. 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.
Commands: stty(1) Functions: ioctl(2) Interfaces: ldterm(7), pckt(7), streamio(7). delim off
