OK I tried the modem, using and old USB Sportser 28.8. The thing has
the following lights: AA, CD, RD, SD, TR, CS, and ARQ/FAX. It made
no difference if I was in command more or connect mode. I did issue
an ATZ command and I don't have any phone lines connected. All I had
to measure time is an old horse trainers stop watch; accurate but
1/5 second increments. The TR and CS lights are always on. When I
issued the Break Command both the SD and RD came on -- for 1 second
with "output \b" and two with "output \l". Since you said the TxD
(which I'm taking to be the same as SD on this modem) should come on
but nothing else I'm assuming that either Keyspan or Kermit or the
MacOS is generating and inappropriate signal.
I have also found that I might have some timing issue where I
connect and don't seem to be able to communicate with the device at
all, but just get messages like "Can't send character: Undefined
error: 0 " I can exit out of kermit and get back in but I do seem
to ofter wind up in an envrionment where key strokes are either
being delayed or ignored.
In repsonse to two other issue: I've never seen a Mac Null Modem
cable, everyone uses printer cables -- but that doesn't mean it is
the same as a printer cable.I don't think it matters. And I was
using the correct control characters but often not getting the
correct responses.
