There is a problem with the vt220 emulation of MS-DOS Kermit 3.14.
I downloaded the beta 14 version, specifically to test the feature
which DEC refers to as "non-erasable characters".
I prepared a small unix shell script to send the escape-sequences
and tested the response in Kermit and in Crosstalk mk4.
---snip---
#!/usr/bin/ksh
fg="\033[2\"q"
bk="\033[1\"q"
cf="\033[?2J"
echo "${fg}foreground${bk}background${fg}foreground${bk}background${fg}${cf}"
---snip---
The expected result, which Crosstalk did provide, is a blank screen
with the shell prompt toward the top, and the word "background"
twice on some line of the screen.
Kermit however, responds with a blank screen with the shell prompt
towards the top. The "background" words are erased as well, which
should not happen.
Kermit did respond correctly to a couple other small tests.
I hope this can be fixed for this version, it's the only
vt220 feature I need which Kermit does not support. Yet :-).
