Tandy didn't wire it right. There are instructions on how to fix it that 
were available on the net way back then. I might even have them printed 
out, someplace in the midden heap that passes for a full basement.

If you do it right, with a 6552 so I can still use my mouse too, you will 
sell me at least one of those dual port kits. Put the ports on a db9 
each, and make the 7wire protocol std.

One of the more famous faults was that hardware flow control stopped the 
transmission in its tracks, in the middle of sending a byte. The 
hardware hack to the pack fixed that too.
