Thanks Mark... I played with this. I built a 3-wire cable; I'm sure I
have it wired right because traffic happens - and if I disconnect, or
switch Rx/Tx, it just sits there.... but this is as far as it gets:

MikeUpstairs:~ Imac$ ./tu58 -s 38400 -p /dev/tty.usbserial -d -v -m -x

(I ctrl-c the VAX)

(I ctrl-c the VAX again)

(repeat)

Can you spot me being stupid? Does my command line look sane re.
various options?

(I've trivially renamed the tape image file for faster typing
otherwise it's straight out of the box)
