Hi:
Who's to say which characters are susceptible to 'jerky' presentation.
Not all data appears on the screen.  Some characters may be terminal
(terminal emulator) control sequences which take some time for the
terminal to process.  Delivering these characters to the terminal promptly
will give it a head start and hopefully it may be done by the time some
real (displayable to the user) data comes along from the modem.

In reality, the modems are getting so fast now, they are exceeding the
speed of the itty bitty processor in most dumb terminals (and the often
inefficient terminal emulation software).  It won't be long before the
burstyness is masked by the overload/lag-behind condition of the terminal!
