X.25 pads generally only send packets when they're full, after a
specified timeout or when some significant characters (usually CR and
DEL) are received.  Needless to say, editors like vi don't work very
well (if at all) since, for example, you have to hit carriage return
after every character in command mode.

Pad parameters can be tweaked so that the packet timeout is extremely
short or the packet size is very small (say 1!) but since you are
usually charged by the packet (or kilopackets), this is very expensive.
