After reading mad boys post i had a look at getting the latest driver only as someone mentioned when i checked through tools the manufacturer was unknown,BUT it says model=CNXT V9xPCI modem.Is this Conexant?

  madPentium 23:38 03 Oct 03

yes it is. In actual fact, if you remove the modem, the makers name will be on the chip.

I would say so in short hand

You will probably get a better and more reliable connection if you follow the tips on buffers page 3 tips

"the makers name will be on the chip"

Yes it will be - but it will be the maker of the chip, not the modem. The modem makers name may or may not be on the modem.

Have a look in Win Explorer for a file called System.ini in C:\windows\ have a look see if you have got that file it's in the windows folder

found 2..one just as system and another as system.ini backup.

Then it will work use the System file, not the backup. The entry goes in the 386enh section of the file. To open the file double click on it do not forget to save the file. If it does not work just remove the entry and resave.

This is the bit to follow,

Build a Bigger Buffer

Any modem user has probably received an important transmission with characters missing. There is no way to find and retrieve the lost characters, but you can increase your odds of receiving data intact by adding a line or two to your SYSTEM.INI file. Before starting, it's important to understand how Windows handles incoming data transmissions. Your modem sends the data it receives to Windows' COMM driver. This stores the received data in a memory buffer until your communications program retrieves it. Unfortunately displaying and storing all the received data keeps your communications program working overtime. As a result, it can't always retrieve data from the COMM driver as often as it needs to. By default, Windows sets aside just enough buffer space to store 128 incoming characters. Unfortunately, once a modem has been connected, data flows continuously. Your computer can temporarily stop the flow of data, but doing that takes time. Meanwhile, data continues to arrive and must be stored in the COMM driver buffer. If your communication link is slow, or your communication program is fast, a 128-character buffer might suffice. But with a fast modem or a slow program, it's possible for more than 128 characters to arrive before your program can process them. In that case, the COMM driver has no place to store the 129th character and those that come after it. Luckily, you can expand Windows' COMM buffers. By adding a line to the [386enh] section of the SYSTEM.INI file, you can create a buffer as large as 10,000 characters. Actually since the COMM driver maintains a buffer for each of your PC's COM ports, you can add up to four lines, each controlling the size of a particular port's buffer. Each line should resemble this: COMxBuffer=num Replace the x with a number between 1 and 4 to indicate the desired COM port, and substitute num with a number from 128 to 10,000 to set the buffer size. You have to exit and restart Windows for the change to take effect. Use a text editor when editing SYSTEM.INI. As for how big should your COMM buffer be, if characters are being dropped from incoming data transmissions, create a new buffer of at least 2,048 (2KB) characters. If problems persist, increase the size of the buffer to 4,096 (4KB) or even 8,192 (8KB).
