Abstract:
1. A computer-readable recording medium storing a host-terminal emulation program for a computer to function as a terminal that interacts with a host computer via a firewall and a relay device, the host computer communicating with the relay device using a first protocol, the firewall permitting the terminal to reach the relay device, not by using the first protocol, but by using a second protocol, the relay device providing conversion between the first and second protocols, wherein the host-terminal emulation program causes the computer to perform a process comprising: establishing a new receiving connection with the relay device by using the second protocol immediately after a previous set of data is received from the relay device, regardless of whether another set of receive data is due or not due; establishing a transmitting connection with the relay device by using the second protocol when data is to be transmitted to the host computer in response to an input operation; transmitting, via the transmitting connection, data entered by the input operation to the relay device by means of the second protocol; and receiving, from the relay device via the established new receiving connection, output data from the host computer by means of the second protocol.
