ABSTRACT:
A system and method of transferring characters from a first device through a buffer memory to a second device. A descriptor is read and a buffer address and a buffer length are extracted from the descriptor, wherein the buffer address and buffer length define a buffer of data stored in the first device. The data stored in the buffer is transferred from the buffer to the buffer memory, and from there to the second device. A check is made to determine if the descriptor should be closed and, if the descriptor should be closed, an indication is made that the descriptor is closed.
