Method of improving computer communication speed in key telephone system
First Claim
1. A method of improving the speed of a computer communication interface module in a key telephone system, the method comprising the steps of:
- (a) detecting if control data transmission/reception interrupt occurs or not;
(b) checking start flag in control data;
(c) performing computer communication data polling at interval less than half of a control data processing clock;
(d) receiving or transmitting one byte of computer data during the period of less than half of the clock, if there is an event of computer communication data after the polling; and
(e) checking an end flag, finishing the process if there is an end flag, and carrying out processes repeatedly flora step (c) if there is no end flag.

Abstract
A method of improving the speed of a computer communication interface module in a key telephone system is disclosed including the steps of: (a) detecting if control data transmission/reception interrupt occurs or not; (b) checking start flag in control data; (c) performing computer communication data polling at interval less than half of a control data processing clock; (d) receiving or transmitting one byte of computer data during the period of less than half of the clock, if there is an event of computer communication data after the polling; and (e) checking an end flag, finishing the process if there is an end flag, and carrying out processes repeatedly from step (c) if there is no end flag.
