In order to aggregate the packets, you'd need some kind of
*line-oriented* terminal, i.e., NOT a 'dumb' terminal, but an
'intelligent' one, e.g., the IBM series (the 4-digit numbered ones,
I don't remember the number, but 3870 or something like that seems
close). 

The idea is that in order to group the characters and send them out
only when a linefeed is generated, you have to have the terminal take
care of everything that happens before the linefeed. That includes
backspace erasing, and any other editing and echo. Similarly, more
complex features (such as command-line completion) are nearly
impossible, because the terminal doesn't know what the commands are.

I hope this is useful.
