I work on 60 lines x 120 columns miniterm over 9600 baud.
The speed is satisfactory except one case: when vim draws '~'
in every line on the init screen.  This drawing is very slow,
takes several seconds to fill the screen.

    I took the vim output log and noticed that vim fills every
line with spaces and does not make use of 'el' escape
sequence (clear to end of line).

    'infocmp xterm|grep el' shows that 'el' is defined. (TERM is xterm).
I think the speed can be improved here, the more that the whole
screen was cleared just prior to this ?
