vt100 non-support
At our site, we have two VAX 11/780s; one runs VAX/VMS, the other runs
VM/UNIX. Since the most commonly used editor on VMS, EDT, requires a VT-100,
we have a number of VT-100 terminals. Unfortunately, termcap and the
applications which use it do not seem to support VT-100s very well. In
particular:
1) Worms does not call termcap properly to get the time delays expanded.
Thus, a series of 5's and 2's remains on the screen.
2) The al and dl capabilities in the vt100 termcap entry contain %2's.
In order to delete or insert a line on the VT-100, it is necessary to
change the scroll region and scroll as appropriate. To change the
scrolling region, a line number is required. However, there is nothing
in the termcap documentation that implies that the al and dl capabilities
accept a line number as a parameter. As a result, none of the programs
using these capabilities work on the VT-100. In particular, vi is
unusable.
3) The cs capability is not implemented in any program that I can locate.
If it were implemented, this would eliminate the need to fix problem
number 2 above.
Has anyone else encountered similar problems with the VT-100? Does anyone
have any solutions?
