Hey everyone,
Problem solved! HSEROUT and HSERIN
now work flawlesly. The problem was
the rs232 <> TTL converter. I used a
factory made converter I got with one
of my digital diary's accessories. I used
it for years with various devices and it
worked every time like a charm. Now, I
assumed it had a max232 built in, but
after cracking the case open I found out
it wasn't the case. It was made with SMD
transistors and had no pull-up resistors,
rather it was an open collector type. PIC
MCU's abviously don't like this very much
when used with their hardware USART.
I made a max232 converter and now
everything works 100%. I'd like to thank
everyone for their help.
