More Problems: GPSD

CrackerStealth · 07-18-2003

Alright now I'm having problems with GPSD. I compiled it and just copied is into /sbin. Then I run:

#gpsd -p /dev/ttyS0 -t 4800

I checked with ps -ax and the daemon was running. Next I typed

#telnet localhost 2947

and I don't see any GPS data, in fact nothing really shows up other then telnet connecting to the daemon. So I have two problems here really.

1) I'm not sure if i'm starting and testing the GPSD properly. Am I using telnet correctly?

2) My second problem is a bit harder. I'm not sure what port linux will recognize my serial port as. According to this website(Thinkpad 760el, http://tuxmobile.org/ir_misc.html) ttyS0 and ttylS3 are my infrared ports, but I can't find any information about what the serial port is recognized as. I've alread tried the above with ttyS0 through ttyS5. 6-20 is going to take one long time to figure out. Is there a quicker way to scan for my GPS serial port?

What gps are you using? I use a garmin Etrex legend and a dolorme earthmate both work great. Did you download the newest gpsdrive?

Mine is a Deluo Serial GPS. It worked fine with Netstumbler on COM1 but I had my IR devices disabled. My main problem is I can't figure out which ttyS is my serial port. Since ttyS0 and ttys3 are my IR ports and ttyS0-ttys6 produce no results for GPSD.

Once you telnet to port 2947, you have to enter commands... hitting 'r' should make it spit out data until you hit 'r' again.

CrackerStealth · 07-19-2003

Thanks but still no luck. Tried that on ports ttyS0-ttyS6 and the result was always the same.

r [ENTER]
GPSD,R=1

Still no luck figuring out what my serial port is.

Is there any way to connect directly to the serial port in linux and get the raw data from it, like you would do with HyperTerminal in windows?

Yeah, just do 'cat /dev/whatever' and it will spit out whatever it's getting...

CrackerStealth · 07-19-2003

Well after doing cat /dev/ttyS0 - cat /dev/ttyS30, /dev/ttyS0 is the only one that gave didn't give me an I/O error, but it didn't produce any GPS results.

One thing I noticed when starting up my machine:

Serial Driver Version 5.05c
RQ SERIAL_PCI enabled
ttyS00 at 0x03f8 ( irq = 4 ) is a 16550A
ttys01 at 0x02f8 ( irq = 3 ) is a 16550A

Ok, I don't see any ttyS00 or ttyS01 in /dev. They also don't do CAT. What else could I possible try?

Minicom might be a good starting point, and it sounds like you've tried all the obvious TTYs.

My Thinkpad required me to enable the serial port from the DOS setup utility (on a bootable floppy) before it would talk. Windows can enable it directly, but if you want to do that under Linux you need to get tpctl .

CrackerStealth · 07-20-2003

I installed the Thinkpad drivers and tpctl but when I try "tpctl rs1=enabled" or "tpctl rs1=on" it just says "module for that command not loaded." I tried loading the superio module "insmod superio" and it just gives me an inknown error 1025. As far as I can tell from the troubleshooting file is that the superio module isn't compaditble with my Thinkpad...

After unsuccesfully getting tpctl to work, I went to the IBM website and downloaded the DOS utility disk. I then got a DOS 6.22 boot disk from bootdisks.com and started up my computer in DOS. I manually (using PS2.exe) disabled both my IR and Serial port. Then I changed the IRQ and address of my IR device to COM2 and changed my Serial port to IRQ and address of COM1. I restarted my computer, booted back into DOS and used the PS2.exe utility to enable the serial port then issued the power on command.

After restarting my computer into linux, "cat /dev/ttyS0" produced no GPD results, but if I start gpsd and then Kismet, Kismet is getting a GPS fix, so things appear to be working. Thanks to everyone who helped.
