Bad super serial card?

I acquired a "non-working" Apple IIe some months ago and in the 10 minutes a week I get to work on it I have been getting it going. In reality it was just dirty and required a new power supply. It now seems to (mostly) work and boots ProDos from the Duodisk I have.

When it came to me it had a Super Serial II card loose in the shipping box, not installed. I took the micromodem installed in slot #2 out and installed the SSII card. I then typed IN#2 and got nothing but gibberish on the screen, random beeps and the machine locks up. When I boot the ProDos users disk and look at the slot assignments it does show as "I/O Card". Is it bad or am I doing something wrong?

Thanks!
 
There are two switch blocks on the super serial card that set baud rate and other comms settings, check that all those are set correctly, a good guide for the settings is to look on the ADT page here:

There is also a dip header which selects whether it works in terminal or modem mode. Check that is set to terminal. Also, try re-seating all the removable chips, this has fixed other serial cards I've had.

Thanks, I will double check all of that tonight. I was looking for a way to determine if the card was working or not but I have no software other than a couple of DOS disks or external peripherals to attach to the SSC. I was reading the instructions for ADT as I thought I could use that to get some software on it bfore my CFFA3000 cards arrived in 3-4 weeks, I wanted to make sure the SSC card was working before I spent money on byuing a transfer cable. The instructions for ADT pro said to type in "IN#2" and then press "CTRL-A" and the card should respond with "SSC:" when I do this as soon as I type "IN#2" the machine goes crazy and locks up.
