Thanks Frank;
I've been doing some expermental research and have found the
following. It seems that all functions of the K95 Linux terminal
emulation work except the escape to and from graphics mode (GS and
GE). The termcap (protermcap in Progress) is set to GS=^N and GE=^O
and work on the Linux console. I understand that Linux display codes
are like vt100 and I check the vt100 termcap entries and find GS=^N
and GE=^O and this works if I set K95 to vt100. Lots of other stuff is
broken but the box drawing works with Linux TERM=linux and K95
emulation set to vt100. When K95 emulation set to linux the box
drawing characters are the un-escaped values of G1 through GV. When I
null the escape codes (GS=\000 and GE=\000) and put in corners of +
and lines of | & - both the linux console and k95 in linux emulation
give the same result.
For your information show char yields:

Terminal character-sets:

Are you sure this is not a K95 issue?
Again, any help appreciated.
