ssh serial console history playback on R710 with iDRAC6 Express?

So I finally discovered the SSH access to the serial console using ssh
to the iDRAC6 and the "console com2" command. Beats the socks off the
flaky IPMI SOL protocols - TCP is so much better than UDP for this stuff!
In the documentation I saw a reference to a mechanism for getting the
system serial history buffer to play back by giving the -h option to
this command, e.g. "console -h com2" - this is apparently something that
older DRAC cards have supported for some time. However, on our R710,
this appears to do exactly the same thing as "console com2" - no history
is played back, just the connecting message. I checked and the serial
history buffer is set to 8192 byte (the default) - is there something
else I need to do to make this work?
(By messing around - "console -?" - I discovered that you can give the
-b option to the command, e.g. "console -b com2" and the SSH connection
goes into "binary" mode, where the ^\ escape back to the iDRAC SM-CLP is
disabled, along with possibly other emulation things like backspace
