'RS232 or RS485 communication'
In AN510 Implementation of an Asynchronous Serial I/O must be a bug.
I must step the time delay loops for the right length.
Have you any other idea about Asynchronous Serial I/O?
Thanks in advance

Well, one problem with Microchip's example source is that they've got
the RS-232 signals inverted. (On rs232, 1's are sent as low voltage,
0's as high). A scope is a great debugging aid for programming
The RS-232 lines are reversed, but if you use some MAXIM interface chips,
it reverses the lines also. So you get an inverted invert, uhh, you know
what I mean.
