[amsat-bb] TNC-220 jumper info?

I know its an old tnc but does anyone have info on the jumper settings they can scan and email to me? Or how the com port speed is set? If I can use it to free up one of my newer tnc's for another use that would be great.

Would be nice to locate newer firmware if possible. I have a burner, just need the file.

I ask here because most of the info I found on the net dealt with hams using this tnc for Satellites.

Thanks and 73,
