Celliax.Org

Well, now I have problem sending calls into celliax... same story....

Error sending data... (Resource temporarily unavailable)

I changed my C350 with another 1 and now it works, but I would like to use the 1st too.

It works with the original chan_celliax.c.

I see that working phone is faster than the other not working.
Cant we try to slow down celliax while using ACM modem?

Here some info from phones:
Phone1 (working):
Flex version: SE7636AXXH3063
SW VERISION: R312ULS_G_09.10.1AR
SW DSP VERSION: 00007107

Phone2 (not working):
Flex version: SE6263AXXX109F
SW VERSION: C350_G_09.04.74R
SW DSP VERSION: 0004321

Ciao

Quoted:
..................
1) are you using the same cable for the two different cellphone (it may be a bad cable)?
2) are you using the same USB "socket" (maybe bad USB socket)?
3) can you send here the last lines generated by the console command "dmesg", after the phone stops answering (the lines that have to do with USB disconnect, etc...)
4) can you send here the celliax.conf file?
...................

1) Yes, same cable
2) Yes, same usb slot
3) I recompiled usbcore.ko with debug...

As usual, the other phone works perfectly inbound and outbound (just some echo to called but im working to reduce it)

A friend told me he can update my phone next weak... I hope for the best.

Ciao

I've checked out your chan_celliax.c source code (but im not a programmer sigh)
and I think i've seen the serial line set up the CRTCSCS flow control.

Is that true?
Can I try to change it? How?

Ciao

You have the gift to making *very* entertaining this bug hunt!

Yeah, at this point seems more a driver (or chan_celliax) problem...

But the fact that it works with minicom (that use the same driver) seems to tell that is chan_celliax to be guilty...

So, minicom has not this 16 chars limit?

Have your friend updated the firmware?

Can you replicate all the commands with minicom?

It is very bizarre that it answer OK to AT+CNMI=3,1,0,0,0 it is supposed to be not supported on c350...

Writing one char at time (releasing the cpu between each write) was my best hope for this case, and you think the same, so...
let's try it!

Is modified now in svn, and it works for me (but it was working also without this mod, so...).

Update the sources (cd into the celliax_stuff directory and execute 'svn update').

Then make install, and let's see...

Super!!!
