G400P - MiniCom access?

update to receive smses, just add:
[GSM1]
device = /dev/vmodem0
send_delay = 25

the send_delay, makes every write delayed about 25 ms - because there is no real handshake in pty mode.
to reproduce, stop asterisk, reload dahdi to bring card into sane mode
socat PTY,link=/dev/vmodem0,raw,echo=0,wait-slave,perm-early=666,user=smsd,crnl EXEC:"/usr/local/bin/g4term 2",pty,crnl &
socat PTY,link=/dev/vmodem1,raw,echo=0,wait-slave,perm-early=666,user=smsd,crnl EXEC:"/usr/local/bin/g4term 4",pty,crnl &
socat PTY,link=/dev/vmodem2,raw,echo=0,wait-slave,perm-early=666,user=smsd,crnl EXEC:"/usr/local/bin/g4term 6",pty,crnl &
socat PTY,link=/dev/vmodem3,raw,echo=0,wait-slave,perm-early=666,user=smsd,crnl EXEC:"/usr/local/bin/g4term 8",pty,crnl &

So reading sms from sim card works:

I think - that g4term should not echo commands, as this should work:

Hi, I'm having trouble loading the kernel module opvxg4xx. I installed everything through the chan_extra-2.0.3 install script. Both dahdi.ko and opvxg4xx.ko are freshly built as you can see from the date:
root@smsubuntu:/usr/src# l /lib/modules/2.6.32-33-server/dahdi/dahdi.ko
-rw-r--r-- 1 root root 156648 2012-05-17 16:57 /lib/modules/2.6.32-33-server/dahdi/dahdi.ko

But when trying to load the module:

root@smsubuntu:/usr/src# lsmod|grep dahdi
dahdi_dummy 2760 0
dahdi_transcode 6836 0
dahdi 210885 2 dahdi_dummy,dahdi_transcode

Messages like these usually mean that the versions don't match, but it's all automatically built from your sources. Any idea what could be wrong?

Hi Darko,

Can you do these steps on the command line?

1. /etc/init.d//dahdi restart

2. modprobe opvxg4xx

3. dahdi_genconf

4. dahdi_cfg -vvvv

To make system automatically loads opvxg4xx, you will be able to edit /etc/dahdi/modules, and insert a line `opvxg4xx` at the end of the file. Save and exit it.

[font=Helvetica, Arial, sans-serif]This is my output (I have added opvxg4xx to /etc/dahdi/modules before): [/font]

[font=Helvetica, Arial, sans-serif]Does "0 channels" mean my card is not recognized? With lspci -vvvvv I can see this: [/font]

Ok, my bad. Using modinfo I found that that another dahdi (2.2) was loaded instead of the one I thought it as. After removing that old version, the driver now loads.
