terminfo trouble

[Lars Brinkhoff]

Hello,

I'm trying to write a terminfo description for a peculiar terminal
type, but there are some problems:

1. The terminal uses byte values in the range 128 - 153 (decimal) as
   control codes.  However, some applications, for example Emacs, seem
   to clear the most significant bit.  The version of vi installed on
   my machine doesn't do that.

   Is there a way to indicate that the control codes should be sent
   unchanged?  (The "km" capability doesn't seem to work for this.)

2. In fact all byte values from 128 to 255 are reserved as control
   codes.  Sending a character > 127 can be done by sending a byte
   with value 141 first.

   Is there a way to do this?

3. The row and column addresses are start from zero.  But sending a
   null byte with %c doesn't work.  Nothing is sent.

   Can %c be used for this somehow, or is there another way to do
   this?

Thank you.
