Hi, recently I've had a real hard time getting online, I use a dial up connection. So I ran a little test on my modem, and it said that it was failing its 'loop back test', soo I was just wondering what that means? I was told that my modem was no good sooooo I replaced it, but the new one isn't working any better, and it has also failed its loop back test. Now a friend of mine put my old modem, that was supposedly broken into his computor and it works fine, it even passes its loop back test. So I guess theres just something wrong with my computor? I'm hoping that one of you wonderful people can help me out here. Both modems are made by US Robotics. My comp is 600mhz P3, 128 ram, Win98. Thanks.

can you tell us what com port the modem is installed on?
is it an isa modem or pci
is the com port still installed?what irq,i/o
range is it using?
are you using a serial mouse(what com port.irq,i/o range) or ps/2 mouse?
the irq's for the rest of your setup.
any conflicts showing?
is the software for your modem still installed?
have you tried re-installing your com port and modem?
lots of questions

Loop back test is done with external "loopback plugs" that are connected to your ports and verify that a PC's serial and parallel ports are working correctly. With the plugs, an input/output "loop" is created, allowing the program to send data out of the PC, then receive data back. Without these plugs attached to your computer, you would fail the loopback test. I have no idea why the old modem would "Pass" in your friends computer without the plugs. What was the little test that you ran?

Sorry for taking so long to reply back. The test was part of a diagnostics program that came with the modem. I did what V said and reinstalled stuff (again!), and this time everything works great, so I really have no idea what the problem was. Maybe my comps just wierd. =) Thank you both lots, peace.
