Dave, on your web page you mention "Each board

suggesting that the console serial port is built into the

like tracing the interface connections from the UART
(probably thru some 1488/9
drivers), the datasheet for the 3-1015 is here:

Yes, I'll do that, partly because I'm curious about what sort of line drivers are
on there. Didn't spot any of the usual suspects. Thanks for the link and the
suggestion.
It's a pin-config'd UART, so the config may also be
discernible from examination.
There is a wealth of jumpers around the UART that I assumed were for setting the console
line attributes but if I trace them back to the UART I can verify their purpose.

Well, I guess I should check the validity of old links before I send them out.
That link is no longer valid, but the pdf(s) do still show up with a search on
the site.
