John Hansen's TNCX uses a USB port. Also the Baycom TNC's use a USB port.
http://www.john.hansen.net/PICTNC.htm
http://www.baycom.org/bayweb/tech/usb/usbindex.htm
Also, don't forget a Serial to USB converter is now in the $10 range, so any
TNC can now be "USB" for next to nothing.

I believe Xastir can use USB with no changes to the code. I think
some of the MacOSX users are doing that very thing now.
Windows/Linux laptop users may be doing that as well.
You just change to a different device port in the
Interface->Properties dialog when you set up the device.

Subject: New APRSdos MILE-MARK display

Just posted APRS861.zip on tapr that has a new and improved MILEMARK
display. The old one required you to type in the mile mark and APRSdos
would come back and draw a circle around it. Very useful for placing a
non-APRS station on the map as an object...
Since Mile Marks are a funamental way that the other non-APRS Ham radio
operators report their interstate travel positions, I have always felt it
was very important to APRS. This new method is simply the "MM" command.
If you hit "MM" APRSdos will draw a circle around every 5th, 10th, or 20th
mile mark depending on your RANGE SCALE.
THus it is very easy to see where someone is based on their mile mark and
you dont have to type it in. You only have to identify the STATE and the
Interstate number once. Then just type MM whenever you want to see the MM
overlayu for that interstate...
THis version does not have any other 860-bug-fixes in it, but since now
the "MM" commmand lets you SEE a plot of the entire data base for a given
interstate, then I can ask you the users to give me feedback as to which
points in the data base are off and need fixing. I just fixed I95 and
I75 in Florida while I was there for the TAMPA hamfest.
THe MM.DAT file in my APRS\SYSTEM directory is in TEXT format so you
can even edit the LAT/LONGS of the turning points to fix them or just tell
me "Bob, Tenessee I40 MM 270 to 280 is messed up and I will fix it.
Once we get the file all fixed up, I will ask the other authors to
incorporate it into their code as well so we APRS users can start plotting
the other 98% of mobile operators who only report by MM...

Doesn't work in California. No mile markers. No exit numbers, either.
Never really understood that.

Has anyone hiked the Appalachian Trail while using APRS?
I'm thinking about hiking parts during breaks from school and I would want
to use APRS during Satellite passes to show my position and maybe send a
message or two. Any ideas on how to do this as lite as possible? PDA,
D7A, Small GPS, Solar Panels or AA Batteries? Hmmm... I would also like to
be able to get into a Winlink station and be able to send and receive
message on that as well on HF but I think that is a subject for a different
SIG...
Comments welcome...

Don't know where you were shopping for computers but you are not the
only one. I have seen this comment before and was worried when I decided
to take the plunge and purchase a new laptop.
I went to a few stores and TRIED to find a laptop without a serial port
but was unsuccessful. All the Gateway's that I was looking at closely
had them and ended up with one of those.
I agree serial on MOBO's have become more and more rare, the days of
dual serial ports on a motherboard seem to be gone but there are some
out there that still have a single port. I did have to pass up on one
motherboard about 8 months ago because I wanted serial on it. It was get
serial or have serial ATA. Serial ATA was still new so I passed on that.
Eventually the laptops will all be rid of serial but I don't think it's
full demise has arrived YET.

If you've ever heard Sun's "The Network is the Computer" mantra, this is a
great example of that. Having everything connected via disjoint protocols
and transport schemes only complicates how you compute. We really need to
encourage the people that make Ham devices to move towards Blue Tooth at a
minimum. It would be okay if there is enough CPU power, RAM and power
supply to run an TCP/IP stack over ethernet or wireless technologies such
as 802.11b.
If it's still not clear that the network is the computer, think about the
APRS-IS and how it works as multiple machines doing part of the whole job.
It's important to recognize this evolution in devices and move forward with
it.

Believe I remember seeing mile markers on the 5 in northern California when
I drove it into Oregon where the mile markers most definitely exist. Maybe
the 101 by you doesn't have them. Many major highways in California have
those mergency call boxes which carry some sort of ID.
On the other hand, some states number exits consecutively -- not by
distance. So a universal solution may not be feasible.

To see an example of the Mile Mark overlay in APRSdos and how I use it to
be able to track my fellow non-APRS travelers, see:
http://www.ew.usna.edu/~bruninga/aprs/tampaMM.bmp
The Mile Mark overlay in APRSdos will work anywhere. The only thing
unique to the road is HOW you name it. So I chose the convention of
SS## where SS is the State and ## is the number of the highway. But
this is only a convention. You could label a road as VATPK for the
virginia Turnpike and it would match. But your users just have to know
what name you gave it...
And anyone can add any interstate to the file (though I dont want to
clutter it up with a bunch of local roads that no one else needs)....
But we DO NEED CALIFORNIA. Back in 1990s when I put this in APRS,
California did not have Milemarks, so they are not in the file..
(volunteers?)
The file is simply a Text list of straight line segments that approximate
the path of an interstate. For the 330 mile long I-81 in Virginia, for
example, it only contains about 8 line segments to cover the entire
interstate.
Again, I am only trying to be approximate since I only identify the
location of a mile mark by a 1 mile ambiguity circle anyway. So, as long
as the circle is within a mile of the interstate, I am satisfied...
For those that want to fine-tune any errors I have made, here are some
notes to help you:
1) once you are zoomed into an interestate and want to just follow the
mile marks, remember the M-arrow commands will move the map up down left
and right with just 2 key strokes...
2) Do an alt-S-FORMATS-DIGITAL to toggle the CURSOR position to DECIMAL
degrees. This is what is used in the MM.DAT file. It helps you write
down coordinates suitable for entering into the file.
3) If MAPS are being automatically switched and you want to stay on the
current map even though you are on the edge, remember the MAPS-LOCK
command... (it toggles).
Please do not feel the necessity to FINE TUNE this file. As long as the
circles are within a mile of the interstate, I am sure they are adequate
for the intended purpose (for APRSdos anyway) and so I do not want to
spend a lot of time titivating it for no real net gain, other than making
the file bigger....
Bob
