With the falling Aussie dollar, we expect to see more of these endangered
species real soon.



Humm,
Why use a Max style chip to convert TTL to 232, why not steel the -ve from
the other ends TX line, a cap, diode, transistor and some resistors and off
you go! Ok so there are some problems with this, but the basic idea works,
and now days the RS232 receives don't need to see -ve to indicate mark. This
does save having to power the converter in the Max style chip, and also
saves a bit of money.
