a colleague got an enfora quad-band gprs data card, so naturally I thought I'd test it for Z compatibility!

first had to hack /etc/pcmcia/serial.conf to make it recognised, add this:
CODE
card "Enfora GSM0110"
 version "Enfora", "GSM0110", ""
 manfid 0x01e1, 0x0300
 bind "serial_cs"


the card is a type2 - a tight fit!

using minicom, I found that the modem (/dev/ttyS3) was unresponsive until I set the serial speed to 115200 - odd, 'cos my audiovox doesn't care about serial speed.

I was then able to do the CGDCONT/*99# dial sequence and see the ppp jumble.

When I then tried to use a ppp dialup script for gprs which works with audiovox, when using the enfora it just hangs.

Anyone any clue before I go for the full custom ppp scripts with loadsa debug?

I did add the "debug debug debug" to the /etc/ppp/peers/DIALUPnnnnnn file, tried "cardctl resume ; pppd call DIALUPnnnn" but didn't get any debug output. Hmmm.


p.s. does anyone else find that a gprs modem card has a very bad effect on USB networking - it either hangs or locks up entirely?

p.p.s. the SIM card I am using works perfectly with the audiovox rtm8000 card

I take it that you were using the qtopia network applet with the audiovox?

I had similar issues, with my modem behaving exactly as you describe, but the connection would die before it was completed. Never could track down how the lights could flash properly and it still not work, and I solved the problem so long ago, that I don't remember which of all my tweakings resolved the issue.

What I do know is that if there is respawning of a different tty than the one you are using, begun by /etc/inittab during the boot process, there will be problems, at least in qtopia 1.5.0.

yes, I was using the qtopia applet, worked fine with audiovox, not with enfora, but manual command line with latter worked fine.

the new owner will probably join this discussion when tweaking settings.
