A terminal computer is used to send instructions to a host computer through a public network to open and close application programs and to transmit data between the application programs and the terminal computer through the public network. In order to open application programs, the terminal computer establishes an initial connection between the two computers and instructions are sent over this initial connection to open application programs. The host computer establishes an additional connection for each application program. In the terminal computer, a respective terminal emulator window is created for each additional connection. For each application program, data is transmitted over the respective additional connection using a character-based protocol. In the terminal computer, the data is converted from the character-based format to a bit-mapped graphical format and then displayed in the respective terminal emulator window.

[ What is claimed is:] [1.]1. A method of establishing data connections between a host computer and a computer acting as a terminal computer through a communications network, said data connections relating to a plurality of application programs running on the host computer, said method comprising the steps of:said terminal computer establishing an initial connection between the terminal computer and the host computer using a long-on procedure;said terminal computer creating an initial terminal emulator window for said initial connection;said host computer transmitting a menu of its application programs to the terminal computer over said initial connection;said terminal computer displaying said menu in said initial terminal emulator window; andfor each application program selected by the user of the terminal computer:transmitting a request over said initial connection from the terminal computer to the host computer to open the selected application program;said host computer establishing an additional connection between the host computer and the terminal computer;said terminal computer creating an additional terminal emulator window for said additional connection;transmitting data relating to said selected application program between the host computer and the terminal computer over said additional connection; anddisplaying data relating to said selected application programs in said additional terminal emulator window.
