It's called polling. It must be supported at both ends. Basically the document is left in the machine being called. When the other machine calls, instead of receiving, it asks to send. And the calling machine agrees to receive instead of sending. Insecure in that any other machine that supports polling can call in and collect the document instead. So often a "password" of sorts is programmed in. Then only the machine knowing the (typically 2 digit) password can collect the document. In larger (read expensive) systems somtimes combined with user id to retrieve fax's from a "mailbox". -- Stuart.Lynne@wimsey.bc.ca uunet!van-bc!sl 604-937-7532(voice) 604-939-4768(fax)
