PTB210 at s1 was working up until 2020-04-12,15:23:03, except of course for periods when s1 was probably dead. There are a few messages after that, until 202-04-16,01:29:11, and then they stop. As of the swap of the s9 DSM, nothing has been received from the PTB.

The PTB was set for 7E1, so I've tried connecting to it on s9 with minicom in 7E1, but there is still no response. Maybe a blown fuse, or maybe the PTB itself is dead.  The data messages received in 7E1 mode are recoverable with some code changes to NIDAS.
