Apparatus for resetting a modem with a variety of additional functions
First Claim
1. A reset system for a modem operable in one of a basic modem mode for an exchange of digital data and an additional modem mode for an exchange of specific data in a computer system having an external reset switch provided on the modem and the computer system for allowing a user to reset operation of the modem, said reset system comprising:
- means for receiving information from said computer system;
decoder means for decoding the information from said computer system to generate a first reset signal; and
signal output means having a first input terminal coupled to receive occurrence of said first reset signal, and a second input terminal coupled to receive occurrence of a second reset signal generated from said computer system in response to one operation selected from among a manual reset operation of said external reset switch and an operation of a designated program contained in said computer system, for combining occurrence of said first reset signal and said second reset signal to generate a modem reset signal to a reset portion of said modem for resetting operation of said modem.

Abstract
A reset circuit of a modem which permits the exchange of digital data with a remote modem in a computer system having an external reset switch provided thereon for allowing a user to reset the modem. The reset circuit includes a decoder section for receiving information from the computer system and decoding the same information to generate a first reset signal; and a signal output section having a first input terminal coupled to receive occurrence of the first reset signal, and a second input terminal coupled to receive occurrence of a second reset signal generated from the computer system in response to either manual depression of the external reset switch or an execution of a designated program contained in the computer system, for combining occurrence of the first reset signal and the second reset signal to generate a modem reset signal to a reset portion of the modem for resetting operation of the modem.

7. A reset system for a modem operable in one of a basic modem mode for an exchange of digital data and an additional modem mode for an exchange of specific data in a computer system having an external reset switch provided on the modem and the computer system for allowing a user to reset operation of the modem, said reset system comprising:
-
a first decoder having input ports coupled to receive address signals from said computer system, for decoding the same address signals to produce an enable signal; and a second decoder having input ports coupled to receive modem function selection signals from said computer system and said enable signal from said first decoder, for decoding the same modem function selection signals upon activation of said enable signal to produce said first reset signal; and signal output means having a first input terminal coupled to receive occurrence of said first reset signal, and a second input terminal coupled to receive occurrence of a second reset signal generated from said computer system in response to one operation selected from among a manual reset operation of said external reset switch and an operation of a designated program contained in said computer system, for combining occurrence of said first reset signal and said second reset signal to generate a modem reset signal to a reset portion of said modem for resetting operation of said modem. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A reset system in a computer system having an external reset switch for allowing a user to reset a modem in the computer system, said reset system comprising:
-
a first decoder having input ports coupled to receive address signals from a computer system, for decoding the address signals to produce an enable signal; a second decoder having input ports coupled to receive modem function selection signals from said computer system and said enable signal from said first decoder, for decoding the modem function selection signals upon activation of said enable signal from said decoder to produce said first reset signal; and a logic circuit for generating a modem reset signal to reset operation of said modem by combining said first reset signal and a second reset signal which is generated from said computer system in response to input of either a manual reset operation of said external reset switch or an execution of a designated program contained in said computer system. - View Dependent Claims (15, 16, 17, 18, 19, 20)
