Ryan,

right you are.  Well, I managed to figure out that ttyS1 is what will be
displayed when using sol activate.

However, if I do a sol activate and get access, and on the server for
example do "echo -n a > /dev/ttyS1" on the server which has IPMI, only
garbage is printed on the sol terminal.  Running getty in various modes
also fails with these character issues.

Got any suggestions?
