14,400 is one of the standard speeds. That number means that the modem is capable of sending or receiving 14,400
bits per second under perfect conditions. Which is 1,800
bytes per second. A megabyte is 1,048,576 bytes, so to send one megabyte of data (with no compression, and ignoring that there are bits used for parity and other overhead, and that real world speeds rarely match theoretical maximums) means that it will take 1048576/1800 seconds-- or 9 minutes, 42 seconds. A 14,400 modem is by definition not able to send an uncompressed file larger than around 80 kilobytes in 45 seconds. To be able to send a 3 megabyte file in that time would require it to be compressed by 38x.
