 Posted: Thu Apr 07, 2005 3:49 am Post subject: palm Vx serial problems |
 |
|
I've searched around the forums, but couldn't find a problem quite like this. I have an older Palm Vx that still has the serial interface, and it has always worked just fine in linux for me, absolutely without a hitch, until suddenly it stopped. I hadn't sync'ed for probably almost two weeks (break from college) and when I returned it wouldn't sync anymore. As far as I know, I haven't made any significant system changes, maybe just emerge'd some updated programs, that's about it.
Here is some relevant info:
It works just fine on a friends windows box, using my palm cradle/cable etc, so I know it's not those.
I use a genkernel (still haven't gotten my own compiles to work quite right), but it is loading the modules "parport" and "parport_pc" as it should.
/dev/ttyS0 looks to have the proper link and permissions, and /dev/pilot is linked -> /dev/ttyS0 (or piped i guess).:
| Code: | lr-xr-xr-x 1 root root 10 Apr 6 22:37 pilot -> /dev/ttyS0
lr-xr-xr-x 1 root root 5 Apr 6 22:37 ttyS0 -> tts/0 |
Tried as root, as the main user in the tty group, neither work.
Here's the output from setserial:
| Code: | setserial /dev/ttyS0
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4
|
dmesg doesn't give me any weird output, just this for the parport stuff:
| Code: | parport0: PC-style at 0x378 (0x778) [PCSPP,TRISTATE]
parport_pc: Via 686A parallel port: io=0x378 |
Also, I just booted into an old Knoppix cd and was able to connect to the palm (but some permissions looked different?), so I guess it can't be the hardware ... so I'm not sure exactly where to start at all now I guess. It's just odd that it was working just fine before. I'll also go through some logs and see if I've emerged something that could have messed things up, but I don't think I've done anything else.
Thanks in advance,
~Andrew |

the devices are linked, not piped. It's just the filesystem telling that this file (/dev/pilot) is just another name for /dev/ttyS0, which is just another name for /dev/tts/0.
So the thing you should check is the permissions of /dev/tts/0.
Mine are: | Code: |
lrwxrwxrwx 1 root root 5 Apr 8 13:21 /dev/ttyS0 -> tts/0
crw-rw---- 1 niels tty 4, 64 Apr 8 15:40 /dev/tts/0 |
Usualy the links should have 777 permission, but I don't think that matters.
The device itself should have rw permissions for your user. In my case I appear to be the owner and clearly have rw privs. |

Here are my permissions ...
| Code: |
lr-xr-xr-x 1 root root 5 Apr 6 22:37 /dev/ttyS0 -> tts/0
crw-rw---- 1 azwr tty 4, 65 Jan 1 1970 /dev/tts/0

Seems okay? And I've tried as user and as root, and tried using dlpsh in pilot-link with port settings of /dev/pilot, /dev/ttyS0, and straight to /dev/tts/0 ...
[EDIT] ....hmmm... i found a program 'logserial' and it's showing that the computer is receiving data on /dev/tts/0 when i press the hotsync button ... i'm wondering why the programs like dlpsh and jpilot aren't working then ... even if i point them to /dev/tts/0 [/EDIT] |

Just using dlpsh from the pilot-link suite for testing, normally i use jpilot.
dlpsh gives me this error:
| Code: |
Error accepting data on /dev/pilot
|
and jpilot this error
| Code: |
pi_accept Invalid argument
Exiting with status SYNC_ERROR_PI_ACCEPT
Finished
|
i'm going to try playing with rebuilding pilot-link again maybe, because i know jpilot just uses pilot-link. |

| still no luck ... just a quick bump/update. i redid my gentoo installation from 2005.0, mostly just because i didn't exactly know what i was doing the first time so i wanted the experience again, but my pilot stuff still doesn't work. i'm waiting for some responses on the jpilot mailing list, but i still can't figure out the problem. it shouldn't be related to udev or anything, should it? i wouldn't think so, being a serial device... |
