ming = blown.I have heard of a boolean implementation which had true as -1 and false as 0. The reason was that -1 has all bits set.
And comparation was done via unsigned instructions, so truefalse even if true-1 and false0;) Although I like Pascal’s implementation the most, true1, and “for b:=false to true do” was fun.
Two serial ports on the back of a PCConsidered to be one of the most basic external connections to a computer, the serial port has been an integral part of most computers for more than 20 years. Although many of the newer systems have done away with the serial port completely in favor of connections, most still use the serial port, as do some printers,. Few computers have more than two serial ports.Essentially, serial ports provide a standard connector and protocol to let you attach devices, such as modems, to your computer.
In this edition of How Stuff Works, you will learn about the difference between a parallel port and a serial port, what each pin does and what flow control is.
