Having trouble installing a piece of hardware? Want to know if that peripheral is compatible with Linux?

modem..falls asleep..?

My problem is a modem which "falls asleep"'s a hardware modem (somehow old one), and works quite fine except this thing: sometimes the connection dies (and sometimes this happens even if I normally try to disconnect) and when I try to re-connect, the only thing (for example from Kppp) I get is the following messages:

Modem Ready
Initializing modem...

and that's it. Normally after that would come "Calling xxxxxxxxx..." and so on, but at times the modem seems to fall asleep and does nothing: the program tries to get the modem dialling but it doesn't.

When opening the phone, for example, in this case the sound tells me that the line is not open. It's like the connection would be open, except that it isn't. Everything else is "offline", there's no pid for Kppp or wvdial or whatever I try to use, but modem is online having a dead connection which can't be neither used nor disconnected. The only way to get it closed is to reboot.

Is there any way to get the line closed without rebooting the whole machine (my modem is internal, so it can't be "unplugged" to get the connection die)? Or would there be a way to prevent this "sleep" from happening? It's annoying to reboot the whole PC just to get modem work....

if u can look in your modem manual or look at it while can send it commands and they shoudl be listed in the manual or on the manufactorers website...some example commands are :

ATZ ---> init modem
ATDT --> dial this number

hope that helps

yeah I've heard of that, and I've found the place where I can send those commands..but the problem with that is that it won't react in any way, like it wouldn't like to receive them? hmm but I think I'll try to figure out what causes that...

thanks anyway
