>> whether or not its possible to send faxes over broadband cable <<
of course it is
as long as u have the internet and a computer
EDIT: Oh sorry, CORRECTION: its not possible.. dont even know why I said that... but there shud be some services on the net which lets u upload the pic and they'll send the fax, possibly free of charge
for fax via dialup modem in winxp without third party software:
go to Control Panel and open the thing normally use to Add/Remove Programs. then click on Add/Remove Windows Components, and give a tick on the Fax component. u may need to insert the winxp CD.
after its installed, it'll be under Start > Programs > Accessories > Communications.
if u want to send fax, u can print it from any program.. Fax will appear as a "printer".
