That is exactly what you are supposed to do, and what I just tested
using two machines connected via a serial connection.

Correct. This is what you should expect.

The receiver was definitely not in LABELED mode. The receiver was probably
in BINARY mode. This is how a LABELED file would be stored in that
situation.

Do us both a favor and try a simple test. Perform the file transfer again
this time transfering a single file and let me know what happens.
Again, I just tested this by sending about a dozen files with EAs from
one HPFS system to a FAT system with no problems.
As far as a CKOCVT program goes, no there isn't one. However, on a single
machine you can use two C-Kermits connected via NAmed Pipes to perform
the translation for you.
See the CKERMIT.INF file for more info on LABELED mode and Named Pipes.
