thanks prakash
one more thing i installed ubuntu and it detects my internal modem as conexant hsf modem.i configured wvdial and gnomeppp and put the modem as attached to ttyS0 AND WHEN I TRY TO DIAL OUT IT SAYS attempting to connect modem but after sometime it says modem not responding .any ideas how to configure this thing??
meanwhile i downloaded the scan modem tool and also the linuxant driver for my modem and got it working.during installation the driver said that already configured modules are available and should it use that or install any new thing..i allowed it use the thing already present on my system.but now the problem as you all know is linuxant only offers 14kbps connectivity for their free version and its very slow so i want to achieve net connectivity without using those linuxant driver.is it possible??anyway ubuntu recognises my modem as conexant hsf in device manager..i liked ubuntu so much.so if somebody can help me out please do.if its not possible i plan to buy an external dialup modem probably dlink.so thanks in advance for all of you guys..
