NMEA-serial port
Hello,
Is it possible to have 2 navigation programs running under Windows 98SE at the same time, using NMEA on the same serial port (com1) Thank You Philippe |

Search on "virtual serial port" and you'll see some examples. Maybe there's a 98SE version out there. Alternatively, you can add a serial port to most machines cheaply. USB/Serial converter, PCMCIA card, whatever. You could then drive both ports by tee'ing off the cable. What two programs are you trying to run? There may be other options. __________________________________________________ __________ Glen "Wiley" Wilson usenet1 SPAMNIX at world wide wiley dot com To reply, lose the capitals and do the obvious.

... I was trying to run Raytech 4.1 and MapSource (Garmin) at the same time Tricky combination, depending on what you want to achive. If you only want both programs to receive data from the GPS, the trick of adding an extra serial port with a serial-usb converter will work. Be aware though, that Raytech needs the GPS to be set to NMEA while MapSource probably wants the GPS on Garmin protocol. If you need to send data to the GPS too, it gets more complicated. VirtualPlex-1 takes care of that, since it works with NMEA data only and it can buffer up sentences from more applications and queue them nicely to be sent to the real port. But with a separate real serial port, you would have to decide which application may send data back to the GPS and hardwire that particular port to the RX input of the GPS. Meindert |
Yea, he's right...if you have 2 serial ports in your PC, great. If you have a laptop with only one port, I'd go the route of the PCMCIA Serial Card. I havent seen any USB adaptors that work 100%. Serial Ports cant be shared, just so you know. So if you want the second program to use what the first is using, it wont work.

How many do you want? I can supply you with adapters that even prevent the crazy mouse problem in XP and win2K. Serial Ports cant be shared, just so you know. So if you want the second program to use what the first is using, it wont work. With a software utility you can. You can use Serial Splitter from www.eltima.com or VirtualPlex-1 from www.shipmodul.com. The latter will also allow all applications to talk back to the one serial port. The only problem for the OP is that he runs Windows 98. Both utilities only run on NT4, 2000 or XP. Meindert |

So if you want the second program to use what the first is using, it wont work. Just so you know, SCSI is a serial interface that supports multiple devices. Que? SCSI is a parallel interface that works with device addresses and a master/slave protocol and bus arbitration. Quite different from a serial point to point link as with NMEA. Meindert |

If you're an advanced programmer, here is an explanation that will help you write your own: http://www.netrino.com/Connecting/2000-02/ Being a programmer in this example is not enough, they also use a PCI interface chip to mimic the registers of a serial port. This is a solution that would even take a few days to weeks for an experienced hardware and software engineer. To write an entire software solution, it would take about 2 weeks for an experienced programmer. And experienced in this case means that he has experience in writing device drivers in Windows, which is an art on its own. Meindert |

I told you to search on "virtual serial ports" because the people who do what you are looking for generally call it that. GPSGate, VirtualPlex, OckamSoft, and others use the terminology. Even the Eltima Serial Splitter product refers to the ports it creates as virtual serial ports. As you've realized, Eltima's VSPD does something else entirely. The "terminology collision" is unfortunate. __________________________________________________ __________ Glen "Wiley" Wilson usenet1 SPAMNIX at world wide wiley dot com To reply, lose the capitals and do the obvious.

Maybe the solution is to upgrade to windows 2000

I did a search for a freeware virtual serial port program when this thread started the other day and was surprised that I could not find one for windows 98. There was quite a few for 2000 and XP and maybe even a freeware or lower cost shareware one. When you go to w2k (try a Workstation version, stay away from Server editions) spend a little time getting everything in the Windows Classic display mode, and turn off all the Display as a web page stuff. With that and a few more tweaks, it will look almost exactly like Windows 98. Another advantage of w2k is the ability to better control some of the finer aspects of networking and the various services that were much more obscure under 98se. As an example, for the most part, popup ads can be controlled by turning off services that you probably don't want or need anyway. And in w2k, the Administrative Tools allow you to look at and control many aspects of your hardware and software. Good luck with that!
