Luc,
Your laptop may have a treminal program installed already, but that may not be the easiest solution. You have two easy choices; GPSUtility at http://www.gpsu.co.uk/ or http://www.gpsu.co.uk/ both have real good NMEA input screens, but you have to get one (both can be free), install it, and then find the NMEA input screen.

@i39g2000cwa.googlegroups.com: what is a terminal program? remember, you are dealing with someone who knows NOTHING! thanks for great information. Some day, I may actually get it! Luc If you have a new computer, there won't be any serial port on it to play with. USB has replaced old RS-232 and 422 ports on most all computers, now, thank you manufacturers. If you do have a serial port, a 9-pin serial port, you can hook the Garmin to it by hooking the port 2 Garmin (green wire) to the serial port's data input on pin 2 (pin 3 on the 25 pin old USB connector). The pinout of serial RS-232 (and other info) is great on: http://www.arcelect.com/rs232.htm You can also buy a 9-pin serial port to USB converter cable for $50 from: http://www.etronics.com/product.asp?...00&sbvname=293 or other places on the net. This is a way to get the archaic NMEA system hooked to a new laptop computer with only USB ports on it so the nav software will work with it. Ok, Garmin green wire is hooked to pin 2 of the 9-pin serial port, Garmin ground's black wire is hooked to pin 5 of the 9-pin serial port as shown in the webpage's great picture. Now we need a "terminal program" to put it on the screen for us..... In Win XP click START - PROGRAMS - ACCESSORIES - COMMUNICATIONS and click up HYPERTERM, Microsoft's dumbest dumb terminal program. Ignore it asking you to make it the telnet program it wants to be, click NO. Then, ignore it asking you to give it a name for this connection, click the popup window's X to close it. Click FILE at the top of Hyperterminal, then PROPERTIES to bring up the New connection properties window. The Connect To tab is on top. Click the arrow on the right side of line CONNECT USING and pick the com port you're using. I only have COM3 on my Emachines mainframe. Ok, the other stuff for dialup modems greys out and now click CONFIGURE button to bring up the port settings page. Micro$not's system is too stupid to sync on any com port speed, so you have to pick it. Pick 4800 Bits per second, 8 data bits, NONE parity, 1 stop bit and Flow control set to NONE so Hyperterm ignores normal serial port flow control connections stupid NMEA doesn't support. Click APPLY then OK. Click OK, again to close the original popup window and at the bottom of the main Hyperterminal window you should see: Disconnected....Auto detect....4800 8-N-1...and some greyed out stuff. If it says this, the screen will fill with NMEA sentences very rapidly if the Garmin is talking to it. If it's working, click FILE then SAVE AS and give it a name like GARMIN TEST PORT and a filename to save this configuration to disk so you can just click it up next time you want to look. Hyperterm is now listening to the COM port and typing whatever it hears, even gibberish or binary gibberish or Garmin gibberish to anything connected to it...at 4800 baud. You now are using DOS 1.0's dumb terminal program from 1981...(c; If you REALLY wanna see Hyperterm go crazy, pick one of the USB ports something fast is connected to, like your USB mouse or webcam! It's all gibberish...(c; To give the grandchildren something to do, hook it to the USB keyboard port so they can have type and read practice.... Did that help? I should be in tech support!...(c; |

Hyperterminal is included with Windows and will work. Tera Term is a better program and is a freeware.
