Corrupted files

You may have transferred a binary file in ASCII transfer mode ; this can result in strange characters appearing in the file (such as ^M) or in damage to the file.

Make sure you transfer text files (such as .txt, .html, .htm, .cgi) in ASCII mode and most other files (such as .bmp, .jpg, .exe, .zip) in binary mode.

If you still have problems, verify that you have "hardware flow control" enabled on your modem. If you are not using the Microsoft TCP/IP stack (part of the Windows XP, Vista, 7, 8, or Server 2008 operating system), contact your stack vendor.
