Right!
COM1 and COM2 are real physical ports, an internal modem cannot be connected to these, only external devices. Hence internal modems connect to COM3, or the next virtual port available.

349355 2005-04-27 23:41:00 Well that could be anything, The ISP, the modem / line noise if u use 56k.

If the modem is OK now on COM3, it wont make any diff on COM1.

my parents pc is on the same line, doesnt have any problems at all.like i can surf at pretty good speed but when i want to download stuff my download speed is crap, especially on p2p :xmouth: it used to be good. :rolleyes:

i would like COM3 in the device manager so i can do those "tweaks"

349356 2005-04-27 23:48:00 What modem do you have? There have been a few cases where the latest MS modem driver has screwed things up. PaulD (232)

349358 2005-04-28 03:19:00 i would like COM3 in the device manager so i can do those "tweaks"Don't know whether you will be able to change your modem to COM3 after you install the new port but if you are game enough to fiddle you can install COM3 by going to Add New Hardware and installing it. After Windows has searched for new hardware, tell it you have already installed the hardware then scroll down to the bottom of the list to Add New Hardware > Install from a selection I choose > Ports (COM and LPT) and follow your nose from there.

349359 2005-04-28 03:41:00 If your HAM modem is using the COM3 "port" it's an internal modem, and it's just called COM3. It's a PCI device, not a COM port. So it talks to the CPU at PCI speed, not at 115k bit/sec or any other standard serial port speed.

COM3 does not exist. As a hardware RS232 serial port, anyway. ;) It exists only as a logic level parallel PCI interface on the modem card, with a driver which makes it behave like a serial port so that legacy software will work with it.


If the modem seems slow, there's a problem somewhere. If it works at all as "COM3" the "port name" isn't the problem.

349361 2005-04-28 07:04:00 If u have XP SP2 installed, this will also lower the amount of open ports, especially with P2P, to stop worms/viruses .

I think before SP2 it was 20, with SP2 it went down to 10 .
