My three-year-old Dell 4400 came bundled with a fax program, "BVRP Phone Tools, Version 2.17d." Initially it worked fine. Recently I had to reformat my hard drive. After reinstalling this fax software, it no longer works. When I try to send a fax, it pops up a window that says "com port unavailable, or being used by another application." At the same time a small window in the main fax graphic says "Modem Manager disabled." I cannot find Modem Manager anywhere in the program, or in Windows fax help. I have already checked the BVRP support page. With the exception of one unrelated driver, I can find nothing specific to my version of this program.
I have already disabled my firewall and antivirus scanner to no avail. Additionally I disabled a browser accelerator program, as well as "Call Wave." This is a program that transfers my phone calls to my computer screen. I thought perhaps this program was occupying the com port, but even after disabling all of these, the problem persists. By the way I use a Lexmark X73 all in one machine. Apparently it includes fax software, though I have never used it, and besides my "Phone Tools" fax program worked fine originally, and that included the installed Lexmark printer. Can't think of any other info I can give you at this juncture. Please help!
