Well, resetting the serial ports using the system utilities worked for a little while in curing my serial port problems but now they are locked up permanently. DTR is on permanently and when the comm program is set to 2400 baud the send and receive lights are both held high, so I KNOW somethging's really wrong. I'm going to be out of commission for a whil. I'm afraid the local apple dealer won't be able to do anything but a motherboard swap (ouch). I can live without the serial ports, I guess, but it's a pain not being able to use the printer.

A similar experience happened to me. I have an early Apple IIc, and I just bought a 2400 baud modem. I could see from the indicator lights that I was sending and receiving data, but there was no output to my moitor. After many phone calls, I was told that Apple recognized a problem with the IIc's serial ports, and they would cover the charges for a motherboard replacement. My local dealer was able to make the repair. I was disappointed when this did not releave my problem, and it was then I discovered that the IIc requires a null modem cable. I just thought you might be interested in hearing about Apple picking up the bill.
