I forgot to mention that even if it were true (and it isn't) there are still
ways to get your Umlaute across 7-bit connections:
1. Use German ISO 646 as your 7-bit character set instead of ASCII.
Suppose, for example, you use DEC MCS on your local VMS computer;
then tell VMS C-Kermit to "set terminal character-set german dec-m".
2. Use ISO 2022 character-set designation and invocation rules, the
most obvious rule in this case the one that uses SO and SI to switch
between GL and GR. Of course this requires something on the far end
to do the switching; if you have such a service that you can connect
to, C-Kermit handles the SO/SO switching on the client end, just as
a VT-220 or higher would.
But again, none of this should ever be necessary. Without actually going
back and looking at the RFCs, I believe that the NVT definition does not
restrict you to 7 bits, it only guarantees that you can use 7 bits, but
does not guarantee you can use 8.
