Have you considered sending an email message instead of a fax? Since you're willing to make a phone call, it could just as well be to an ISP or a customer's machine running an SMTP server. The SMTP client protocol is rather easy to implement. See RFC 821. I think there are even email to fax gateways. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: The PICList is archived three different ways.
