Ben,

As I told you over the phone this MACPIC is not something I can help with
as it
is not my baby. However I can tell you that you certainly need to use the
resistor mod on the cable as the MAC serial port is not RS232 but RS
something,
something, something  with the differential voltage levels. The resistor
forms a voltage divider required to generate differential levels from the
GND to
5V levels generated from the warp-13.


Typing in "a" should not bring a response from the warp-13. It is not
part of any of the protocols and it is ignored. Type ALT-128 (on the
numeric keypad) and you should receive either , (or * depending on the
firmware version)
