I don't want to shoot down your efforts, because it is out of innovation
that new things come, but is there any reason you aren't using "off the
shelf" solutions for any of this? e.g. a GPS (or NMEA from existing onboard
GPS receiver), OpenTracker or TinyTrak3, & a radio onboard the sailboat,
and something like UI-View for the IGate... or for that matter, just use
the existing IGates in the area? If the object of the exercise is to write
some code that will be useful to you, and possibly to others, then go at
it. However if you want something that is tried and tested, there is
already lots of hardware and software out there. Go one better and use
something like a HamHUD onboard the sailboat instead of a tracker and it
would be capable of sending and receiving messages too... assuming the
sailboat is manned by an amateur radio operator. The HamHUD kits aren't
available right now, but the parts and plans are. As others have suggested
a D700 could be used too. Other solutions... a laptop running UI-View
onboard the sailboat with a GPS receiver connected to it and almost any TNC
and a radio. Even DStar would do the job if there are DStar repeaters
onshore all along the course. If it's just a matter of tracking the
sailboats, a transmit only device like the OpenTracker or TinyTrak3 would
be the simplest solution. Just some thoughts, and I'll go back to watching
the posts to see what you end up doing. Perhaps you are writing code for an
IGate.
PS - some of your posts are in HTML format. You could also change from
top-posting to bottom-posting and do some serious trimming so there isn't
the entire text from the reply and two previous messages along for the
ride. Just leave enough of the previous reply in there so people know what
you are commenting on.

Subject: [aprssig] telnet client
Does anyone know of a telnet client for win32 that can be commanded from a
command line to send a text file upon connecting to a server? The
application is to allow a program I've written to create some info on some
aprs objects, then make a telnet program connect to the aprs IS (or local
server copy of aprs) and send the data line by line. It would then
disconnect and return to the command prompt.
Any ideas?
Wes

I'm trying to do it this way for the following reasons.
1) I was told that it would be easy.
2) The Orbcomm boat positions reports can be emailed anywhere.
3) VHF APRS coverage is poor in the middle of Lake Michigan (especially up
North).
4) I don't own the boat I'm racing on. If it were my boat I'd have HF and
VHF ham gear on board.
5) There are other hams (in this race) that are racing and might want to
have their boat tracks on APRS.
6) I've done tracking on 144.39 I've never done it this way.
7) I was also told that forming the logon string and forming the packet is
the hard part, the rest is easy. Well I've done the hard part. I just have
to figure out how to logon to the proper server and upload the packet. I
have no idea how to do this last step.
I'll keep you posted 73 Bill N9TN

Windows had a telnet client; not sure how scriptable/controllable it is.
It may not be too difficult to make your program create a TCP socket and do
it inline, but I don't do windows programming so I can't give any advice.
Sounds like you really want a perl script. (: I've used ActiveState's
version of perl, and a quick check indicates it comes with
IO::Socket::INET, so you don't have any extras to load. The example code
below creates a DF object and changes the bearing to the target a few
times; maybe it's good enough to be of some use.

The telnet client that ships with Win2K is a command line utility.
It *appears* to send a text file if appended to the command using

Ah... I get it now. Data from the on-board GPS receiver is sent via
Orbcomm's LEOs to you. www.orbcomm.com

Subject: RE: [aprssig] telnet client
There is. I used to use it all the time. It'll do exactly what you're
talking about. It's worth noting that there's a difference between a raw
TCP connection and a telnet connection, though. Telnet will do some
negotiation (using WILL/WONT/DO/DONT tokens) for terminal parameters and
such. However, if it fails, it doesn't care - it'll always fall back to a
dumb 'network virtual terminal'. So you can use Netcat to connect to a
telnet server, though as I recall you can't be sure a telnet client won't
send some extraneous bytes when you connect to something non-telnet with
it.
But yeah, netcat's what you want.

may try to block it as a hacking tool. Which it can be, but the same goes
for ping.
