>Anyway, before I close this, do you know of any good modem software for the Apple //e?
Sorry, someone else will have to help you with Apple IIe software.
>Also, I have an iMac G3, and I was wondering if there was a way to somehow connect the two to transfer files. I have AppleWorks with the communications program on the iMac, and MacTerminal 2.2 on the Mac Plus.
There was an old Apple support article (22229) about how to connect an earlier Macintosh computer to an iMac for file transfers. The software used (on both sides) was ClarisWorks 5.0. This is an approximate adapted summary of the method described:
1. Connect the modems with a phone cable.
2. Open a new ClarisWorks communications document.
3. Connection settings for both computers:
Method: Serial Tool
Baud rate: (try appropriate rates)
Parity: none
Data bits: 8
Stop bits: 1
Handshake: (try appropriate methods)
Port: (choose appropriate ports)
4. File transfer settings:
Protocol: XMODEM Tool
Method: MacBinary
Transfer options: Standard
5. On the receiving computer, select a receiving folder.
6. Open the connection (in order to be able to type AT commands).
7. Type ATD on the sending computer.
8. Type ATA on the receiving computer.
9. The modems should begin to negotiate.
10. When connected, select Send File from the Session menu on the sending computer.
11. Click the Send button.
12. Select Receive File from the Session menu on the receiving computer.
13. The computers should begin sending and receiving the file using XMODEM.
You could adapt the above method to suit your needs. For example, a program like Terminal 2.2 could be tested on one or both computers (with the necessary handling changes). Also, using a terminal emulation program with ZMODEM file transfer capabilities on both sides will make it easier to establish a connection.
My experience with a direct (local) modem-to-modem (RJ-11 to RJ-11 cable) connection is that it is not at all sure that the modems really begin negotiating. In order to make it work, a line simulator is often needed. Basically, one can build a very simple line simulator from a (modified) standard RJ-11 to RJ-11 phone cable, a 330 Ohm resistor, a 9 Volt battery and a battery contact. A line simulator is only for a direct local connection, NEVER for a connection to the public phone lines.
>I tried using a basic telephone cable connected to the Apple Personal Modem through the "wall" port on one end, and the iMac internal modem on the other end.
That should be OK, but a line simulator may or may not be needed.
>The Mac Plus is connected to the modem through the Modem Serial Port.
Yes, that would be the normal way.
>There is no telephone cable plugged into the other port on the Personal Modem.
OK
>I tried using this setup, but I can't seem to get the iMac to communicate with the Mac Plus. Are there any settings that you suggest I change?
See above.
>What is the other phone cable port on the Personal Modem used for?
As I understand it, one port is for the phone line and one for a telephone set. I do not know whether there is an actual difference between the two ports.
