BPS (Bits Per Second). This is the
speed of a modem. Roughly speaking, divide this number by 10 to get the raw burst
speed of the modem in CPS (Characters Per Second). You will often see the term
Baud erroneously used as a synonym for BPS.
A 1200 BPS modem can send about 120 characters per second, a 2400
240 characters. How close to the theoretical speed you achieve depends on your
protocol. Zoomit and ZMODEM are very close to 100% efficient. XMODEM can be as low as
10% on packet nets.
