[comp.sys.cbm] Another Kermit Problem

kykerr@k9.cs.orst.edu (Ronald Kyker) (01/13/89)

	I'm having problems with the delete key in connect mode on kermit.
     Outside of connect, the INST/DEL key will delete a character.  In
     connect mode, it sends a .  The CLR HOME key seems to take over the
     function in connect mode, but I'm getting used to using the wrong key
     for backing up (text adventures are getting anoying).  Is this a bug
     or do I need to set a parameter somewhere? Thanks for the help!

That's the way it is supposed to work.  Kermit redefines some of the keys
to implement ASCII codes not normally available from the Commodore keyboard
and to emulate a VT100 keyboard.  The basic redefinitions are:

	<left arrow>		escape
	<up arrow>		caret ^
	F1 or <shift =>		underscore _
	F2 or <shift B.lb>	bar |
	F3 or <shift @>		back tic `
	F4 or <shift up arrow>	tilda ~
	F5 or <shift +>		lf brace {
	F6 or <shift ->		rt brace }
	<B.lb>			backslash \
	<clr>			^L
	<home>			^H backspace
	<del>			delete (rubout)
	<inst>			break

So, what you are seeing is typical for a system which interprets ^H as the
'backspace and erase' character.  I don't know how easy it is to change this
in Kermit (also depends upon the version you have, I imagine).  You might also
be able to change it on the other end- depending upon the system to which you
connect (ask a system operator).

The problem is the delete vs back space problem.  Some system use delete;
other systems use back space.  (Some programs are nice and take both.)
Kermit (C64) sends a delete for the INST/DEL key.  It sends a backspace
for CLR/HOME.  (Kermit on my PC sends a delete for backspace and a
backspace for ^H; at least the C64 version gives you a key.)

	Kermit has several delete keys.  I believe "INST/DEL" is ASCII
delete ($7F), while F7 is Backspace ($08).  CLR/HOME may be another
key, as you mention, but I don't know.

	Various systems respond in different ways.  Some systems want
a DEL code, others will accept backspace.  I'm mildly used to using F7
here for a delete.

	In any case, they are different codes and I suspect your
favorite UNIX system can be tuned to accept something that is
acceptable to you.

It sounds like a problem with the system that you are connected to and
not with Kermit. Not all machines have the same idea what a delete character
is, so my guess is that Kermit is sending what it thinks is the delete
character to the machine, but of course, the machine thinks it is some
other character and sends back a '.'. This is only a guess though, you
neglected to say what system you are connected to when you have these
problems. If its a mainframe, then chances are you can set it up to
interpret the delete key as such.

Mail me if you need further help...
