I had an ESS 2839 Modem, that did not work on my linux Fedora Core 2, so I had to buy a Softlink Modem (code SL 1900).
It worked well just after I bought it, but now, it start to make me sick. When I use the ESS modem under Windows, it connects well, but when the Smartlink is used, it does not detect a Dial tone, and it makes a very high tone beep.
Though, on the ESS, the line is working properly. So, I thought the line wasn't good enough, so I bought a brand new wire, but it still didn't work out well.
On the Phone, when I exchange the two wires (polarity, may be), the phone also make the high tone beep, but while polarity is inverted, the Smartlink still doesn't detect any tone beep (and the same under Linux for this Smartlink modem).
So, what is the solution for this problem, because It's making me sick, now I'm in a CyberCafe to post this message, because the line seems to be bad. I called the phone service (on a public phone) and they sayd, they'll come to see what they can do.
But, before they come, I should have a solution ready for the modem, if it happens that the modem still doesn't detect a dial tone, even after fixing the whole phone line. The idea also is that I use Linux, rather than Windows XP, so, I need the Smartlink modem to do that.
