I have been trying to get my plug n play card to work correctly with linux for a while now. I can can actually dial my ISP or some BBS board successfully. The problem is that I cannot stay connected for no longer than a couple of minutes before I am disconnected, and returned an error 'No Carrier'. If I am quick enough to get a file to download, I will stay connected until the file is completely downloaded, then I'm disconnected. I assumed then that the CPU provides the plug n play card with some continuous signal to ensure online connection via Win95, which I also have
installed on my system. I then went and bought a cheap 33.6 modem card to test this assumption. The result, actually turned out to be the same. That is when I am disconnected, I recieved the error 'No Carrier'. This isn't a real easy problem to solve, and would expect a detailed answer that would explain what the problem is; how it can be solved; and if it can't be solved what are the alternatives. Also is there a way that I could "fake" the modem into thinking that it has a signal in order to stay connected. I am thinking to do this, I probably would need to write a device driver, something I would like to not do if possible.
As for checking noise on the telephone line, it is about as clean as it is going to get. I also disable call waiting when I dial out, so call waiting is not the cause either. Also, I cannot find any interrupt conflicts that may be causing this problem, so I suspect that this isn't the problem either.
I need all the help that I can get on this matter to solve this problem.
