I have a Dell desktop with Broadcom internal modem. 56K V92. The driver
appears to be up-to-date.
I have my phone line plugged into the computer, then a jumper line goes from
the modem over to my desktop phone.
When I try and fax, say, a MS Word document, the cover page goes, but
nothing else. I get an error that the fax failed, but the cover page shows
up at the destination, without the documents.
Also, if I send a single cover page, I get the error message that it failed
to send. However, the fax does show up at the destination.

I went through the XP troubleshooting guide, to no avail. Any suggestions?
