You guys have been a great help, the picusart.zip and the other serial
routines have been great, but I am having ZERO luck getting them to work.

The bitbang method is a method is a variation on
http://www.piclist.com/techref/piclist/cheapic/alpha4m.asm .

I used the formula from the code to get the timing right. I have only tested
the send routine, and I tried using Hyperterminal in 'view data' mode.  I
also tried the mscomm control in VB6.  I get nothing with both.

One of the problems is that I am using a 20mhz resonator on both chips
(16f84a & 16f628)
I would really like to get a bitbang routine to work with the 16f84 and the
USART going on the 16f628. 4mhz is the fastest 'proven code' that I have
found.  I don't really know what I am doing wrong and would love to have
code that is proven, so I can rule out hardware issues.  I have seen several
formulas for baudrate, my resonator seems to be off several milliseconds
(using Roman's on the dot 1 second routine).  Between these two margins of
error, not counting my inexperience, I am stuck.

Should I just go ahead and buy a couple MAX232? Like digikey # 296-1402-5-ND
?
For only $1.30 for the TI brand it's not bad.

I would also like to order a 20mhz crystal, but don't know which one. Do I
need caps?


Thanks again.
