TL;DR: In this paper, the first and second flip-flops and logic gates are controlled such that the first data source to present a RTS signal is awarded priority and thereby selected to receive a Clear-to-Send (CTS) signal from the modem.
Abstract: An electronic module including a logical interlock for interconnecting two data sources to a modem whereby only one of the two data sources is allowed to transmit data at a time. First and second flip-flops and logic gates controlled thereby are provided such that the first data source to present a Request-to-Send (RTS) signal is awarded priority and thereby selected to receive a Clear-to-Send (CTS) signal from the modem. A subsequent RTS signal from the non-selected data source is ineffective in establishing communication with such non-selected data source since that source is blocked from receiving a CTS signal from the modem. A clock signal is effectively employed to ensure that simultaneously-generated RTS signals from the two data sources are only responded to by one of the two data sources.

TL;DR: In this paper, the modem sharing device of this invention is provided with a plurality of DCE serial ports 2, 3, 4 and a DTE serial port 1, personal computers 107, 108 and 109 or the like are respectively connected to the DCE ports and a communication unit 106 such as a modem or a TA is connected to DTE port 1.
Abstract: PROBLEM TO BE SOLVED: To use one modem to allow a plurality of terminals to make PPP connection at the same time. SOLUTION: The modem sharing device of this invention is provided with a plurality of DCE serial ports 2, 3 and 4 and a DTE serial port 1, personal computers 107, 108 and 109 or the like are respectively connected to the DCE ports 2, 3, 4 and a communication unit 106 such as a modem or a TA is connected to the DTE port 1. Upon receipt of a PPP Configure-Request frame or a PPP Terminate-Request frame at the DCE ports, the transmission of a frame is controlled depending on the establishment state of the PPP connection of the terminal.

Abstract: Disclosed are a modem sharing device of a PDA phone capable of
efficiently sharing a modem by constructing one parsing module respectively
attached to a plurality of applications of the PDA phone in order to parse
commands of the plurality of applications, and a method thereof. The modem
sharing device of a PDA phone comprises: a plurality of applications; one parsing
module for parsing commands generated by the plurality of applications and
distributing; a transmission module for transmitting the distributed commands
through one port; and a modem for receiving the transmitted commands.
