Patent ID: 7124218

Claim:
A method for executing full character interactive input/output mode communication at the application level of a TCP/IP protocol stack in a half duplex block mode environment requiring a half duplex block mode interface between a client workstation and a server, comprising the steps of: operating said client to communicate in said application level over said half duplex block mode interface with a first server application written with half-duplex block mode architecture in half-duplex block mode; operating said client to communicate over said half duplex block mode interface with a second server application requiring full duplex character interactive mode by: receiving a key stroke into a buffer at said client workstation; automatically transferring said keystroke from said client workstation over a half duplex block mode interface to a full duplex character interactive input/output server application; and said full duplex character interactive input/output server application processing said keystroke and responding appropriate to context of said full duplex character interactive server application; thereby transferring single key strokes as they are entered at said client workstation even though operating in said half duplex block mode environment in which character sequences are normally transferred.
