Windows XP Driver for Dynalink External Modem 1456VQE-C.
After Installation, you can verify it pressing the "Query Modem" button (under Phone and Modem Options/Modem/Properties/Diagnostics). If it fails, turn off the modem and after waiting sometime (say 30 secs), turn it on again, Retry "Query Modem". It should work atleast it worked for me.
