A specialized file transfer interface on a ASCII to 5250 protocol converter that provides improved data transfer performance and integrity is herein described. Personal computers with an asynchronous interface attachment can be attached to a 5208 either directly or through asynchronous modems (see the figure). Software necessary in the PC to provide ASCII terminal emulation can be extended to provide the ability to transfer files between the host system and the PC. To provide optimum speed and data integrity, a special interface between the PC and 5208 was designed for file transfer. This interface is activated by placing the 5208 in data transfer mode. Data transfer mode in the 5208 is turned on and off using the ASCII commands DLE STX and DLE ETX.
