|Is it possible to use echo to send a vt-100 escape sequence in v6/v7/sys\
|vr2?
|
|I can write a c program to clear the screen and go home in sysvr2:
|
|#define ASCII_ESC 27
|main()
|{
| printf( "%c[2J", ASCII_ESC );
| printf( "%c[H", ASCII_ESC );
|}
|
|and it works fine. I can type the escape sequences in as well, but I'd
|just as soon write a shell script with an echo '[[2J;[[H' or something
|similar without having to compile a clear command. Is it possible and
|what do I need to know :)?.
cat is considered harmful.
Is it???
