way OT: vsifax

[Enrique Arredondo]

Does anybody knows how to make vsifax for unix to use the PREFIX="9W" and 
then not use it depending on the fax it's using ?

I have like 6 faxes connected to the unix box in which only one has a 
direct phone line not requiering the "9" to make calls.

I tried:

FXPREFIX="";export FXPREFIX;echo "hello" | fx -dmex1 -n 7140000000

but still it's using the main profile's FXPREFIX="9W".
