Since I first went online in 1995 I've used internal modems. Now, since I'm a frequent DOS user and we're losing ISA slots, I've converted to using an external modem.

My Courier works a treat. But I have a couple of problems with it. These are OS specific (I multi-boot).

Windows 98
If the modem is powered on and I'm not currently connected to the Internet then my computer momentarily locks up each time the phone rings. I have "Auto Answer" disabled on the modem via dip switch but presumably Windows is being distracted by the COM port activity? This is really annoying if I'm playing a 3D game or whatever. Is there any way to stop Windows from noticing the phone ringing or do I have to power down the modem whenever I'm not online?

Windows XP
The modem is not installed in Windows if it is not powered up when I boot the OS. The only way to then get it recognised is to power the modem on and reboot. Isn't there a quicker way?

I realise that both these issues could be fixed with the judicious and timely use of the modem's power switch. But I'm just not that organised...

Any help welcome.

TIA

Well with XP this is a known problem and microsoft knows about it.

Please post a modem log with OS 98.Make sure that "call waiting" is disabled.Might also check the log to see if the modem is not set to auto answer. S0=0 disable auto answer
What is the make and model of the modem?

The modem is a new USR Courier 3453 which I bought off eBay at a bargain price form Germany. I then changed the country code (using VEverywhere) to UK which is where I live. Here's a modem log-

Thanks for the info on XP. I suspected it was an OS issue.

The problem in Windows 98 is that the lock up exists exactly during the time of the actual phone ring. So the lock up goes on-off on-off in time with the ringing. Any suggestion appreciated.

TIA

How much ram do you have on this system? Do you have any fax software or other related modem software running in the background. Click ctrl,alt,delete and see what is running in the background.use the system configuration utility and go to the start up tab.Remove the check mark to any program that you don't want windows to load at startup.Do not remove system tray or explore.This was a big problem on some compaq pc.Do you have wake on ring set in the bios?Also check if the modem is sharing an IRQ with another device.

Hi Charles,

In answer to your questions (the mystery deepens methinks)...

1/ 256 MB

2/ No fax or comms software running. I run a very clean system regarding StartUp and registry "run" options. I'm quite fastidious about it. I hate the arrogance of programmers who think their programs ought to be running all the time. The is a clean, lean system and has plenty of free resources. The phone ring lockups are not just occuring in relatively demanding 3D games. The mouse locks up momentarily on an empty desktop when I've got 80%+ system resources free.

3/ This isn't a Compaq system. I built it and it's stable and well configured.

4/ Wake on ring is disabled in the BIOS.

5/ The modem is on COM1 which has IRQ4 all to itself.

Thanks for the ideas. I think it's a tricky one!

Display settings 1152x864x32 (I have a 19" monitor) and no nic card.

I only have 95% free resources on boot but I do run PowerStrip and a couple of other utilities that I've found indispensible.

I think I'll just have to make sure I power the modem off when I'm playing 3D games and suchlike.

Might turn down the display to 16 bit high you should not see alot of change in what you see.

As to Win98 lockup when phone rings -
sounds like you may have some kind of conflict in the serial port.

The external Courier will send "RING" through it's serial interface if on and the line rings (if DTR & CTS are high). If you don't have any software running and the port is closed, DTR should be low and shouldn't be lit on the modem. You can change the behavior of the modem as far as sending 'RING' when the line rings with various init strings, and can also vary with DIP switch settings. So, if the problem relates to the modem's 'RING' response, you may be able to affect it my eliminating 'RING'; however, that shouldn't be necessary - the system shouldn't be affected by the modem ringing.

The other thing - I'm not too familiar, but doesn't the UK use a different wiring scheme for phone lines, and do you need a special adapter to connect the line?

Aloha! Richard.

Hi Richard,

the DTR light goes out whenever I disconnect. Only MR, RTS and CTS remain as you'd expect (and HS after I've been connected).

I have a proper USR cable for this modem (don't ask me what they charged me for it...) so it is correctly connected for the UK phone system.

Maybe it's time for a Windows 98 format and reinstall now I've got good operating systems on other partitions here anyway.

When your modem senses a call coming in, it sends the result code RING to your computer, goes off hook, and negotiates for a connection. If there is no response within 60 seconds, the Courier 56K Corporate modem hangs up.
For more information about adjusting the 60-second wait-for-connection time using S-Register 7
Might try lower the S7 to a lower number.Default is 60.
