telnet linemode has the Set Local Characters (SLC) function. The 
telnet(1) manpage says:

     slc state  The slc command (Set Local Characters) is used to set or
                change the state of the special characters when the TELNET
                LINEMODE option has been enabled.  Special characters are
                characters that get mapped to TELNET commands sequences (like
                ip or quit) or line editing characters (like erase and kill).
                By default, the local special characters are exported.

(And I confirmed the "By default, the local special characters are 
exported" part by doing stty erase '#', telnetting to a NetBSD machine, 
and seeing that erase was set to # on the remote machine. You don't 
have to type "slc export" yourself)

Either sounds OK to me... I've removed the tset from my .login and 
things are working well for me now. ssh works fine, and serial console 
has erase ^? by default, which is correct for me. If FreeBSD removed 
the tset call, perhaps that's what we should do too.
