check for bad modem port?

My modem port no longer seems to work on my 68K Quadra 900. OS7.5.5, OT1.1.1 and OT/PPP. Connected to an AppleTalk network via Ethernet (just 2 machines).

Tested the connections, lines, cables and modem on another machine, and all worked okay. Tried another modem on the Quadra, and got the same error messages while trying to connect. ("Modem not responding, you should've voted Libertarian").

Any way to test the modem and printer ports? TechTool 1.1.3 thinks they're okay. If they're bad, is there any way to fix them without replacing the motherboard?

Did you try a terminal emulation software (e.g. Zterm) to directly communicate with the modem? Does it echo what you type? Did you check baud rates? Most modems do have LED which flash with in/out going data. Does your modem show any such reactions?

No, I don't really know how to use terminal emulation software. I think I might have something on ZTerm (from Global Village). What do I need to do?

I have tried other modems in both the modem port and the printer port (yes, I pointed to the right port in the communication software I use). None worked on my machine, but all worked on another machine.

I've heard of software called MacTest Pro that can be used to test these ports and other stuff on the logic board. Anyone have any ides how to get it?

I have never heard about MacTestPro. There is TechTool Pro 1.0.4 which can test hardware. This is a commercial product and you will have to buy it ;-)
You were refering to TechTool 1.1.3, in my opinion this shareware application cannot test the serial ports.

Get Zterm, start it, select the port your modem is connected to. If things are correct you can type AT and then press enter and the modem should answer with OK. Many modems also react to At&V and display their configuration. If you can do this then your serial port is OK.

Let me know how far you get.

Hey, that works pretty good on this PowerMac. Can't try it on my Quadra, which has the suspect ports, because it seems to have died.

For pxh only: Resubmit any ol' comment as an answer and you get the points.

Thanks!

Resubmission of the old comment:

Glad I could help you,
