vt100 for tandy model 100

[Jim Rendant]

Have you ever  tried using VI in open mode? If you have you know the
problems of editing a file. It seems as though when using SCO xenix the
TRS100 termcap definition will only let you use VI in the open mode.
Has any one seen a VT100 or above emulation program for the Tandy model 100 
portable computer? Matbe a modified termcap entry.
I have checked to see what the minimal controls that are necessary to take
VI out of open mode, they all seem to be there. For some reason it still
doesn't work. 

If any one has a solution to my problem please drop me a line.
I welcome any response and thank you for your efforts.
