5x00 Hardware / Gps Problems

« on: August 31, 2005, 03:03:54 pm »

It might be worth persisting with the "stty" command that I pulled out qpegps. See what format of the command
 "stty 4800 line 0 min 1 time 0 ignbrk -brkint -icrnl -imaxbel -opost -onlcr onlret -isig
-icanon -iexten -echo -echoe -echok-echoctl -echoke < /dev/ttyS3" actually works
without errors. You might be able to get away with entering that command just before starting qpeGPS.

Interesting.  After deleting the arguments that caused errors, I got this:

Code: [Select]

root@poodle:/# stty 4800 min 1 time 0 ignbrk -brkint -opost onlret -isig -icanon -iexten -echo -echoe -echok-echoctl -echoke < /dev/ttyS3
root@poodle:/# qpegps
card ready
port settings ok
So it eliminated the error message, but I still get a red GPS status in qpegps.  I guess some of the arguments I deleted might really be necessary, or the problem is gpsd.  I might try the alternate version of gpsd now, though I never did get any NMEA output from a telnet session with that one.

For my problem, I reviewed the various fixes posted for Haicom GPS cards that Ian linked to.  They seemed a bit involved and difficult to reverse, so I decided to see if my GPS card would work with zRoadmap first.  It does!  

This leads me to believe that my problem with qpegps is indeed related to the version of stty in OZ 3.5.3, and possibly gpsd.  My end goal is to use qpegps with topo maps, so I will continue to experiment with these.

5x00 Hardware / Gps Problems

I've been watching this thread carefully, as I have the same symptoms (green gpsd, red GPS indicator on SL-5600, Hentges OZ 3.5.3 ROM, Haicom 303-MMF GPS).  I have some different diagnostics, though (note that I'm inside, and don't expect to receive any signal):

Things that look like possible problems, but I'm not sure about:

[bat dead]: it's been charging for a long time, and charged indicator on the unit has come on.  Seems like it's working.

speed 115200 baud: is this supposed to be 4800?

telnet localhost 2947: seems like this is correct output, but I can't read it.

stty: invalid number `line': i have no idea if this is a problem.

cat /dev/ttyS3: binary stuff, not correct?  related to the speed?

One thing I noticed is that my /dev/ttyS3 has group read permissions, and Lee's doesn't.  Could that be part of his problem?

Thanks for any help!
