Title: Another GPS Problem... Post by dufek on Dec 15th, 2007, 6:25pm I have a similar problem as three83 had in a previous post. I have the splitter software installed and I am experiencing trouble with keeping the GPS connection "live". Here are my specifics: Just purchased the program, so I am using the current version from the website. I have a GPS unit coming in to the laptop via a serial connection. I have two programs that use the GPS data coming in. I tried both sharing and splitting/virtual the com 2 port with the GPS data coming in. At first, it works perfect, but after a time (maybe 30 minutes), both software pieces stop receiving data. If I restart the computer, it works perfect again for a short time, then the data stops going through. Before the splitter program, we only had one piece of software using it and it worked for 8 hours straight, so I believe it is a problem with the splitter utility or its setup...help! Please advise any suggestions. Thank you. |

Title: Re: Another GPS Problem... Post by Andrew on Dec 17th, 2007, 5:06am Hi! Let's see what happens there. We need investigate serial traffic to know exactly why that happens. Usually we use portmon program to monitor serial traffic. Please download it from here: http://download.sysinternals.com/Files/PortMon.zip Please use the following portmon setting: Edit -> Max Output Bytes -> 1024 Options -> Show Time [x] Options -> Show Hex [x] Options -> Clock Time [ ] 1) Please split COM1 to COM3, COM4. 2) Launch portmon 3) Configure portmon to capture data from physical COM port: Capture -> Ports -> COM1, COM3, COM4 4) Launch communications programs (on COM3 and COM4) and work with your device until the issue appears. Then close communications programs. 5) Save captured data to file: File -> Save As -> serial.log Please send us serial.log file. Thanks! |
