Subject: clarify how modems on serial ports attach, and their corresponding
 device numbers; inspired by a thread on misc@, and my own, er, experiences..

 A speed of 115200 should be specified
 if you have a modem capable of bit rates of 28800 or more.
 In general, the serial speed should be about four times the modem speed.
