It is not amateur radio when these cases are modified to:
1) a GSM phone connecting to a commercial provider and you making a call
to another amateur
3) a PC connected to the Internet and using cordless keyboard or mouse
operating on amateur radio frequencies
6) a cordless phone is constructed to work on amateur radio frequencies
and to make a phonecall while you are in the shack, using the cordless
link to communicate with the base station in the living room.
8) an amateur radio link is used to connect a machine on the Internet
(probably connecting to some chatbox, a voice interconnect etc) with
a local operator using amateur radio frequencies.
The obvious difference between your examples and these, is that the main
part of the link has nothing to do with amateur radio.
Phone patches are not amateur radio, and in fact they are only allowed
in a few countries. Most amateur radio license conditions preclude them,
or in fact any other connection to other external networks.

Subject: MFSK16 relay tests, 100% copy!
Hi all, I had some very encouraging results from the relay tests I ran
on Sept 9,00.
MFSK16 did very well indeed and we were able to get 100% copy on all
the test that were run. I was running about 12 watts output to a
inverted V dipole up 9 meters. This type of antenna could be set up
very easily at just about any portable site.
One of the best samples of how well MFSK16 did is in message number 63
at:
http://www.egroups.com/group/psk31relay
Message 63 was sent from my Orlando QTH and received by Sandy, N2SF at
his NY QTH - a distance of over a thousand miles!
There has to be some public service potential in that! The ability to
send a accurate message more than a thousand miles using free
software, a soundcard that most computers already have and a HF rig.
Then have the message posted for public viewing quickly.
The only item that is required that a lot of hams might not have is a
good laptop computer.
I run a Compaq 200Mz laptop and they can be bought used at very good
prices.
It's pretty easy to justify the purchase of a laptop computer because
they have lot's of other uses besides ham radio.
Well, that's all for now.

Has anybody here in the states bought/built one of these 'yam' modems?
I did not see any reference to a KISS mode, anybody have any more info than
what's at the site listed??
I was into the 9.6k baud packet stuff for about 2 years till the guy running
the local tcp/ip switch pulled the plug, I built and tested 2 of the TAPR
9.6k modems, modified and tested a couple of Motorola Micors to work with
them. I am now looking to use something similar to do remote control via
packet.

I heard that was on hold or shuffled off to some commercial use for a few
to make bux on, and the amateur end was lost in the shuffle.

The YAM modem is a MODEM, not a TNC. Thus, the reference to a KISS mode
is irrelevant. It does modulate and demodulate the HDLC bits.
This is in fact a situation preferable over KISS.
In some situations, it may be useful to have a TNC with firmware running
(e.g. for standalone telemetry stations, maybe for APRS although I have not
seen suitable firmware for that, etc).
In the normal case, however, today's PCs have much more power than a TNC
would have, and it is best to leave the AX.25 protocol handling to the PC
instead of inserting a TNC between them.
