Title: GPS
Post by three83 on Jan 17th, 2007, 8:28am
I'm using serial port splitter to run 3 applications that access the same com port.  Connected to the com port is a gps.  Sometimes it works great other times not so great.  When it stops working I am unable to get NEMA data from the GPS.  If I stop the serial port splitter software I will start getting NMEA data, then if I restart the serial port splitter software no NMEA data.  Generally after serveral reboots it will start working again for a while then the same thing happens.

Hi!
First of all, what version of Serial Port Splitter do you use? Please check if it the latest version.

Second question: is your GPS a serial device or USB device. I mean, is it connected to physical serial port, or does it create virtual COM port?

One more question: what access rights settings you've configured for split COM ports and what is priority signals COM port setting?

Awaiting your reply.

I'm running Version 3.6.4 of Serial Port Splitter

The GPS is a serial device but is connected to the PC with a USB to Serial Adapter.  It is using COM2 on the computer.

We are not splitting com ports we have com port 2 shared.

Thanks.

1. Is it possible to send us screenshot of Serial Port Splitter GUI  as soon as error occurs?

2. Check and double-check you are using 3.6.4 version, because similar issue was fixed in 3.6.4

3. Try split feature instead of share. I mean split COM2 to several virtual COM ports (COM3, COM4, COM5) and use these ports instead of COM2

Awaiting your reply.

There is no error, the applications just stop receiving GPS data.

Verified I am running 3.6.4

I will attempt trying the split feature but I don't think this will work with our applications.

Hi, is GPS port virtual or physical COM port?
Could you please check that the port is present in Windows, the disable/enable Serial Port Splitter and try again.
