Try getting a DOS (command) window and entering that "echo ATHO > COM3" command. If that releases the phone line, we're part of the way.

I go to run and type: "cmd", then type: "echo ATHO > COM3" , without the quotes for both. Still the same. Thanks.

482672 2006-09-05 03:17:00 I manage to type in the terminal command. Basically, create a connection then it will allow to type in the command then I press enter, then the status bar says connected and it keeps counting the seconds. No change. lightfoot (39)
482673 2006-09-05 03:47:00 I got this same problem when the modem was sharing the same time slot as the soundcard...I had to disable the soundcard to see it work...

I shut down, then I just pulled the modem out, rebooted, and let it run a while...

I turned the puter off and re-installed the soundcard (might be the modem that is easier to remove and replace...I don't know about laptops...a different thread on that!).

Reboot and let Windows find the new hardware...and let the wizard do it's thing by not interrupting it doing it!

Since you never turn off the sound until the puter is off, that's why the modem won't let go of the line. The soundcard is also one of the first things to come alive at boot-time.

See if that works...it did for me.

Aha: you need to use the Hypertterm just to send commands to the modem; not to use the modem to connect to anything. :D It's a bit messy to persuade HT that you don't want a real connection, so that's why I gave the simpler straight command.
I think in XP you have to use the Start/Run sequence then give that command.com or cmd.exe. That gives the "black" "DOS" screen with a prompt.

482675 2006-09-05 04:58:00 p.s. XP might need the colon on the end of "COM3:" ; DOS was never very fussy about that. XP might produce a file, which wouldn't be helpful, if the colon is missing. Graham L (2)
482676 2006-09-05 05:06:00 It is a laptop with I think internal sound card. Just tried to disable the sound card but same.

I tried going to black dos prompt to give the command you gave a few attempts back then, but no good. Thanks

482677 2006-09-05 05:13:00 i have come across lappys with the wiring on the internal modem input plug 'reversed' as they were originally intended for a different country......you might check out and invest in an adaptor ? drcspy (146)

There are only two wires used. US phone systems use the centre two pins on a 6 pin connector; NZ (and other UK influenced countries which use the BT connector) use the two pins on either side of the centre two. Most computers and modems have the US style connector, and the adapter cable going to a BT plug does the change. If it's wrong (two wires going to the centre two pins on both plugs) the computer can't possibly cause this problem. It wouldn't have any connection to seize.

482679 2006-09-05 05:37:00 Hi Guys,

Guess this might have already been covered, but worth double-checking . . .

. . . symptoms described are exactly what would happen if the ph cable were connected into the Laptop's Network socket (which looks almost identical to the Modem, just a little "wider") .

Other things to check - does the modem respond OK to Windows in-built diagnostics, and is it set to "New Zealand" (many laptops come with a utility to change the country setting to match local dial-tone) .

Regards, Martnz
