Abstract
The present invention is provided by installing a piece of computer software on a Windows NT system to enable the Windows NT system to bypass messages sent by a Unix system while communications are being established over a phone line between the two operating systems. The Unix operating system has a communications protocol which sends out messages during and requires a password and login to establish communications. The present invention provides a port grabbing routine, a skipping routine, a calling program and a Unix emulator to enable the Windows NT system to establish communications with the Unix system without having to alter the Unix system in any way.
Claims15
A method of establishing communications between a first computer and a second computer, comprising:
- (a) obtaining a user login and password;
- (b) initiating communication between the first computer and the second computer by sending the user login from the first computer to the second computer;
- (c) sending the password from the second computer to the first computer;
- (d) bypassing a message sent by the second computer to the first computer;
- and
- (e) establishing a connection between an operating system on the first computer and an operating system on the second computer.
An article comprising:
- at least one sequence of machine executable instructions;
- a medium bearing the executable instructions in machine readable form;
- wherein execution of the instructions by a computer system including a first computer and a second computer causes said computer system to:
- (a) obtain a user login and password;
- (b) initiate communication between the first computer and the second computer by sending the user login from the first computer to the second computer;
- (c) send the password from the second computer to the first computer;
- (d) bypass a message sent by the second computer to the first computer;
- and
- (e) establish a connection between an operating system on the first computer and an operating system on the second computer.
A computer architecture for establishing communications between a first computer and a second computer, comprising:
- (a) obtaining means for obtaining a user login and password;
- (b) initiating means for initiating communication between the first computer and the second computer by sending the user login from the first computer to the second computer;
- (c) sending means for sending a password from the second computer to the first computer;
- (d) bypassing means for bypassing a message sent by the second computer to the first computer;
- and
- (e) establishing means for establishing a connection between an operating system on the first computer and an operating system on the second computer.
A computer system for establishing communications between a first computer and a second computer, comprising:
- a processor within said first computer;
- and
- a memory within said first computer, said memory being coupled to said processor, the memory having stored therein sequences of instructions, which, when executed by said processor, cause said processor to perform the steps of:
- (a) obtaining a user login and password;
- (b) initiating communication between the first computer and the second computer by sending the user login from the first computer to the second computer;
- (c) sending the password from the second computer to the first computer;
- (d) bypassing a message sent by the second computer to the first computer;
- and
- (e) establishing a connection between an operating system on the first computer and an operating system on the second computer.
