How to address Telephone socket on laptop?
Posted on 2007-08-06
I am trying to set up Win 98 SE on a Sharp Actius PCA280 to access internet and e-mail while travelling.
I got all available drivers from Sharp USA and a driver for the modem from the web.
The laptop has a COM port and an LPT port on the rear of the external floppy drive unit. It also has an IR port, a telephone socket (RJ45) and an Ethernet socket.
I have no evidence that Windows recognises the existence of the telephone socket and do not appear to be able to tell the modem to use this socket when it aims dial out.
The Ethernet socket works fine.
When I installed the modem, I was given a choice of only two ports to choose from: COM1 and the Infra-red port - neither of which seems right. When I open Modem under Control Panel and go to the Diagnostics tab, it shows two COM ports. COM1 to which the modem is attached and COM4 (No modem installed). The COM4 port has no interrupt and no address. As I mention above, I was not given an option to install the modem to COM4. Under Device Manager, COM4 is not shown at all. The only ports showing here are COM1 and LPT1. Also in Control Panel is an applet called HSP modem. This gives the port as COM1, shows my location as UK and tries to give me a choice of ports to connect to - COM1 , 2, 3, 4. Unfortunately these options cannot be selected as they are greyed out.
When I try to use the modem to dial a number, The familiar click followed by the modem dialling noise does not happen and the process is eventually halted with a message "Dial-Up Networking was unable to complete the connection" and the subtext "Error 630 the modem is not responding properly, please verify that the modem is plugged in to the computer and the phone line..."
Following the Troubleshooter, Windows attempts to communicate with the modem and reveals "Port is already open", which is not very useful.
I believe there must be a piece of software or a driver which will tell Win 98 that the laptop possesses a telephone socket, and defines the parameters of the telephone socket so that it can be connected to the modem. I do not believe this is the case at present and I cannot find any appropriate solution on the Sharpusa website, nor within Windows 98.
