Can you tell me how you configured your modem to work with BSNL ?
I set the VPI / VCI settings and chose PPPoE. I tried all the modulations but none seemed to work - with some i get both the PC and Link light on the modem ON, but i can't connect the WAN Miniport software thing that comes along with WinXP, i.e. to send the username and the password.
So, please let me know how you did it.
