The changes in Version 1.2 are as follows:

1. Fix version 1.0 & 1.1 CPM Lock

The following errata has been fixed:

"If the receiver opens a new BD and the next character received is a mapped
control character (i.e. a character to be discarded) or the Control Escape
character ($7d), the CPM could lock up or generate an SDMA bus error,
affecting all SCCs. There is no work-around. The likelihood of experiencing
the problem is greatly reduced if the MRBLR field is set to the size of the
largest possible receive frame."
