need help: error opening terminal con80x25 during install

[wybo@servaly.hobby.nl (Wybo Dekker)]

Hi,

I asked this question earlier but got no answer. Would very much like
to try debian but can't run dselect. Please take a quick look... it
can't be a difficult one:

After having installed debian for the first time and logging in as
root I got the opportunity to install packages with dselect.  However,
when dselect started, it gave the message:

error opening terminal con80x25

and quit, leaving me with an almost empty system. 
The TERM variable was indeed con80x25. Changing it to "console" did'nt help.
Does anybody know what I did wrong?

Thanks for helping!
