Windows NT Telnet Uses VT100 for UNIX Terminal Emulation (105234)
The information in this article applies to:
- Microsoft Windows NT Server 3.1
- Microsoft Windows NT Workstation 3.1
- Microsoft Windows NT Advanced Server 3.1

If a user logs into a UNIX machine using the TELNET command from
Windows NT and some screen-oriented UNIX utilities do not function
properly or show garbage on the screen, the user's TERMCAP may not be
set properly. Because Windows NT Terminal (used for TELNET) defaults
to VT100 emulation, the TERMCAP should be set for VT100 on the UNIX
machine.
Use the following procedure to verify your terminal type when using a
Bourne Shell:
- Establish a TELNET session and log on to the UNIX machine.
- Type the following at the UNIX prompt (usually a $):
- Verify that the environment variable TERM is set to VT100.
- If the TERM variable is not set to VT100, at the UNIX prompt, type
the following and press ENTER:
- Type the following and press ENTER:
For most versions of UNIX, this should reset the terminal type to
VT100, and all screen-oriented utilities should function as usual.
NOTE: If you are using a C shell or a derivative, change the set command
above to setenv and eliminate step 5.
MORE INFORMATION
Because UNIX is a multitasking, multi-user operating system, it can
be configured to use many different terminal types. The TERMCAP files
define what terminal-specific information UNIX sends to a terminal for
cursor control (similar to ANSI.SYS in MS-DOS). Screen display
problems may occur if the TERMCAP is defined incorrectly. An example
of a screen-oriented UNIX utility is the text editor program, vedit,
which can be used to test the screen settings.
