Nope, Andy I meant no stopbit.
What effect does putting a stop bit in have on the reliability?

Bryan

(PS It's extremely easy to add one to the routine.)

I hope I'm not butting in and grabbed the wrong end of the stick. I
assume RS232 style comms are under discussion.

The stop bit is required for two reasons that I can think of:

* Timing considerations (the data word is expected to be, say, 10 bits
long)

* Ensuring correct start bit detection. The stop bit is high and the
next start bit is low, thus providing a reliable transition.

Adding extra stop bits (more than one) can't harm things because the
stop bit value is the same as the idle state. Obviously it can knock
performance a bit.

Bryan:

Without at least one stop bit after each character, there's no way to
detect the start bit of the next character.

Hi Richard
Some of the 16Cxx devices have serial communication possibilities built in,
just program the appropriate registers according to the data sheets and
you're running. Beware of the errata sheets though.  For instance, on the
16C74 you're adviced not to use a certain baudrate setting mode.
For the other 16Cxx devices, get application note AN555, "Software
Implementation of Asynchronous Serial I/O", document DS00555B on the
Microchip website.  It gives you both sample schematics and a lot of code.

Good luck
Michael

Anyone has created a working serial rtx routine with auto-baud
for a 16C84??

Buy Myke Predko's PIC book.  It's available from Amazon.com or more info
from http://www.myke.com

It has what you want.  I built one.  Works great!

A quite expensive serial routine.. :-) is this the favourite book
of piclisters? :-) I've readed about it more than four times..
i'll probably buy it.... Thanks.

There's lots more useful stuff than the serial device.  There's IR, CRC,
random numbers, and more.

In other words, working examples (with disk) of everything the newbies on
this list ask for.
