xchen@caip.rutgers.edu (Xinghao Chen) (01/09/91)

First let me thank all the people who sent me massage about setting my
4425 terminal.

Secondly, I need advice on how to use an external modem to connect
3B2/300 computer to other computer networks through phone line.
I have a SPORTSTER 2400 external modem (by USRobotics with
2400/1200/300 baud rate). When I use this modem with a terminal, I
type "atd phone_number" to connect to the network and three
consecutive pluse sign to disable the connection. Now, I need to know
how to setup the system files in the 3B2/300 computer in order to
 1. login to computer networks and work on the network's machine;
 2. transfer files bidirectionally between the 3B2/300 and a network
    machine.
Please tell me as detail as you can about what shall I do. Suppose
that the contty port is used for the exterbal modem. I have the Basic
Networking Utilities installed in the 3B2/300. I also need to know
type what commands to establish and cancel the connection.

Thanks a lot.
