RE: ir transmitter some success

["Ian B" <Ian@xxxxxxx>]

I have a design and code for a 232 to 485 converter from Elector
Electronics
which I was going to use. Free save the components and having to make a
circuit board. All the info is there though so just time. No idea about
232
to 485 cards for the PC and 1U cases.

This is the very code I am modifying!!

How is your PIC programming. Can't think of anything to do at the moment
but
just wondering.
