Try not exporting EDITOR=vi in your profile.  That is the character at a
time read mode.  Gets rid of things you don't like, but at least it
doesn't drop characters over VT.

One way to see what it is doing is to turn on display functions.  You will
probably see a DC1 between each character you type, unless you type
quickly and it drops some chars.

In the non-char at a time mode, you should only see a DC1 when it is ready
for a command line, not between each char typed on the command line.
