I've been using an external modem** and last night 2 or 3 times I got
connection speeds of 4800. Not 48,000 but 4800! I think my first modem was 4800. Today I couldn't connect at all. It said no modem. I turned it off*** and turned it back on. No good. Turned it off from 90 minutes, and it worked again. Got to wonder what will happen tomorrow. :) ***I should have been turning it off when I turned off the computer. I could have plugged it into the UPS even, but after a few days I just started leaving it on, for months. **because for some reason I couldn't get two internal modems to work, one that had been working the previous day on another mobo and one that was new. I don't have another external modem and don't want to buy one when I have 3 internal modems. Maybe I can get one of them to work. |

Google it. Does your PC sees the modem at least? Can you dial into it from yoyr cell phone, etc. to see what happens. |

Today I couldn't connect at all. It said no modem. I turned it off*** and turned it back on. No good. I guess you have removed and then installed the modem drivers again. Do the same with the COM ports in device manager and reboot. Can you flash the modem EPROM? Check for a current flash software. Check the phone line plug on the modem and ensure there is not a bunch of dust affecting the line connection at the wall and modem. If so, blow out with canned air. Line noise can determine the quality of the connection speed for a modem. Turned it off from 90 minutes, and it worked again.

Disable COM ports 2,3 and 4 until you get COM 1 working - my guess or check the BIOS to ensure the COM ports are enabled. I take it you moved these modems from one machine to another. I don't have another external modem and don't want to buy one when I have 3 internal modems. Maybe I can get one of them to work. Pull all but one, get it to work and then move to the next one. Use the Hayes modem protocol to send commands to the modem, as mentioned by Tony. (send the command to turn the speaker on so you can get an idea of what is going on). You can do this in Hyper-Terminal under Accessories Communication. -- Oren ...through the use of electrical or duct tape, achieve the configuration in the photo.. |

Pick up the phone and listen for noise. Punch a number to get the dial tone
to stop. Have you had rain recently? Water getting into the lines can promote noise which kill modem performance "mm" wrote in message ...

Thank you all. But I'm not going to do anything until the next time it doesn't work. I realize now that I wasn't clear -- I apologize -- but I actually wasn't asking for help, just telling you how it stopped working and then seemed to work again after being without power for a while. I thought that would be an incident useful to know about. I should add, that before I turned it off for 90 minutes, I turned it off for about 30 seconds and it didnt' work when I turned it on. And that months ago, I had turned it off for only 5 or 10 seconds on occasion and that it would work fine when turned on again. So it seems like being off-power for 90 minutes really helped. If it had just stopped working, that would have been less interesting, but I thought the 4800 connections the night before were interesting. It's still working now. I disconnected and reconnected once since I first posted. Thanks again. |

Hmmm, I remember acoustic modem you used to stick onto phone handset, LOL! IIRC, the Bell 212A standard (1200 BPS) was designed to not work well with acoustic couplers like 103J (300BPS) was. -- Mark Lloyd http://notstupid.laughingsquid.com "Unlike biological evolution.

Pish. I remember the 256k sticks as new and hi-tech- a big leap up from the tubes of loose chips we had been using- first 9 chips (for $30) to make a 64k bank, and then the leap to 9 chips making a 256k bank. When I bought an extra 24K for my VIC20 (about 1983), it came on a big cartridge (12 big RAM chips and a couple of decoder chips). It cost $150. That's more than my more recent purchase of a 512MB PC3200 module. I used to keep a 'visual aids' drawer at work with samples of all the generations of memory chips, and of CPUs, to show to new kids coming in. One day, some self-appointed arbiter of stuff to keep (stuff she used) vs. junk (stuff she didn't recognize) pitched it all.

I had a PcJr. for like 11 years, but didn't have a modem until maybe I borrowed one the last month, and had no one to call. I think my first modem I used was 1200, and it was fast enough for email and usenet iirc. I remember that 300 would receive text nearly as fast as a lot of people can read. That is, if you don't have to stop to figure something out, as in one place where someone confused "gravity" with "gravidity". -- Mark Lloyd http://notstupid.laughingsquid.com "Unlike biological evolution.
