Peter,

 I own the book "Serial PIC'n" and in my opinion, YES, it's worth
 having.  There are many routines in there for just about any of the
 PIC's, and any protocol you desire.  There are routines for I2C, SPI,
 other three and four wire derivitives, RS232, TTL, etc.  This one
 book should just about take care of all of your serial comms needs
 now and in the future.  And if it doesn't, it imparts enough know
 how that you can write any routines that aren't included in here.
 My recommendation...Buy the book.  You won't regret it.

 As an aside, you may want to consider the other books written and
 sold by David Benson.  ie "Easy PIC'n", Pic'n Up The Pace" and
 one more that I can't recall right off hand.  These books have been
 very interesting for me to read and are now references that I consult
 ocassionally for tidbits and routine ideas.   I do most of my soft-
 ware writing in 'C' now, but assembly still comes in handy in time
 critical apps.  Also, for some short programs that are not
 sophiscated enough to use the higher level language.

 Anyway, hope this answers your question.
                                          Regards,

                                            Jim
