Re: Re: [ql-users] QL serial ports

Ian has said -

I can't remember the exact name
of the book - something like "The Indispensable PC Hardware Book" or
words to that effect.
=====================

A book I have found very useful in the ports-and-pins arena is -

        NEWES COMPUTER ENGINEER'S POCKET BOOK

I have the 2nd edition - Michael Tooley [well he is a 'hardware' man]1989.
RS 232C/CCITT V24 is described in great detail on p184ff

However, in the special realm of our world beating QL ports, nothing in my
experience is better than Tony's advice.  Every such e-mail is archived.
