Abstract
A system for storing and transmitting data comprises a processor, a memory, an output device, a facsimile-modem unit, and a line interface unit. The line interface couples the processor and the facsimile-modem unit via lines to the facsimile machine and telephone network. The processor is also coupled to the computer and a memory, and controls the facsimile-modem unit and the line interface unit. The system stores and transfers data to operate in a capture mode, an auto-receive mode, a fax-modem mode, a printer mode, or a scanning mode. The present invention also includes a number of methods, including a method for determining the operational mode of the data transfer system; a method for capturing and storing facsimile transmissions; a method for transmitting and sending data over the telephone line; a method for sending data for printing; and a method for scanning data for storage.

10. A method of receiving and storing facsimile transmissions in a data transfer system coupled to a computer and a telephone line, the method comprising the steps of:
-
monitoring the telephone line for a facsimile transmission; receiving a facsimile transmission; determining whether the computer is operational; transferring the facsimile transmission from the data transfer system to the computer if the computer is operational; and storing the facsimile transmission in a memory of the data transfer system if the computer is operational wherein the step of storing the facsimile transmission comprises the steps of; determining whether the memory has space in which to store the facsimile transmission; storing the facsimile transmission in a memory of the data transfer system if the memory has space; determining whether the facsimile transmission has an encoded format; and
the storing step is performed only if the facsimile transmission has the encoded format. - View Dependent Claims (11, 12, 13, 14)
