A CIRCUIT AND METHOD OF HANDLING ASYNCHRONOUS OVERSPEED There is disclosed a circuit which compensates for a data transmission speed difference between a local asynchronous terminal and a local data adapter. A remote asynchronous terminal is connected to a remote data adapter, the local data adapter is connected to the remote data adapter through a telephone system. The local asynchronous terminal transmits local data to the local data adapter, the local data contains a start element a plurality of data elements, and at least one stop element. The remote asynchronous terminal receives from the remote data adapter a remote data where the remote data contains the plurality of data elements from the local data. The circuit includes a local serial interface arranged to receive the local data from the local asynchronous terminal and remove the start element and the at least one stop element from the local data leaving only the plurality of data elements. A local controller receives the plurality of data elements from the local serial interface and replaces the start element. The local controller next creates a packet using the start element and the plurality of data elements. A remote controller receives and disassembles the packet. Next, a data extractor extracts only the plurality of data elements. A remote serial interface receives the plurality of data elements from data extractor and replaces the start element and adds a shortened stop element to the plurality of data elements to create the remote data. Finally, the remote serial interface transmits the remote data to the remote asynchronous terminal.
