Has anybody made a easy to use serial chip, all seem
to be lacking some
feature?
The only way I like to program is I/O is 'hardware" setup ... Dip
switches and hard reset
lines. :)
Which reminds me... The HP98036 (serial [1] interface for the 9825, 9835,
9845 computers) uses an 8251 USART. It's initially configured by dip
switches on the PCB, there's a little state machine to load the right
values into the 8251's registers.
