You can modify the behavior of the library by defining an environment
variable named `TVOPT
'. This variable is a set of strings separated by
a space character. Valid strings are:
cyrillic enable cyrillic character set mapping (Linux and VCS only) latin enable latin character set mapping (Linux and VCS only) noarrow disable the arrow pointer (FreeBSD only) nogpm disables support for the GPM mouse driver (Linux only) novcs inhibits the use of VCS to do video output (Linux only)
Examples for the Bourne shell:
export TVOPT=nogpm does not use GPM export TVOPT="nogpm novcs" disables both GPM and VCS export TVOPT= cleans the variable
Examples for the C shell:
setenv TVOPT nogpm does not use GPM setenv TVOPT "nogpm novcs" disables both GPM and VCS unsetenv TVOPT cleans the variable
