TEM provides "dumb" terminal emulation over a full duplex TT:
line. It allows the user to "become" a terminal on a remote
system, and to do ASCII file transfer between systems. TEM has
been used to communicate with RSX, VMS, RSTS, and TOPS-20 sys-
tems, as well as non-DEC equipment. It requires no software on
the remote system (and therefore has no error checking).
In addition to the basic functionality, TEM can automati-
cally issue canned commands to smart modems at the beginning
and end of a session. The user can also select from the fol-
lowing features:
* Local Echo.
* Automatic linefeed on carriage return.
* Translation of inbound control characters to ASCII abbre-
viations.
* Passthru of control/s, control/q, control/o and control/x
to the remote system.
* User selectable attention and end-of-file characters.
* Inbound and outbound character mapping.
* Specifiable record delay and prompt character for file
transfer.
* Parity generation and checking.
* Support for dialout modems as remote devices.
TEM requires at least RSX-11M+ V2.0, VAX-11 RSX V2.0,
RSX-11M V4.0, or RSX-11S V4.0. If running under RSX-11M or
RSX-11S, it requires the full-duplex TT: driver, get/set mul-
tiple characteristics, and unsolicited input AST's. Correct
access of named directories and files numbered in decimal re-
quires the FEAT$ directive. The GIN$ directive is used to pre-
vent nonprivileged users from using TEM to read files that are
none of their business (eg: LB:[0,0]RSX11.SYS). An attempt
has been made to conditionalize TEM for RSX-11M V3.2, but I
have no way to check it. TEM can be initiated from and commun-
icate with any reasonable serial device, but there may be res-
trictions if not being used on a TT:-type device.
