You can create the file in C as a stream-LF file,
then change the file type to binary stream (UDF, no record attribute).
Kermit will be able to handle UDF files unless it goes
out of its way to disallow them.
I haven't programmed VMS in a long time, but I think
changing file types is done with an undocumented RMS function,
or with a disk ACP QIO function. (I don't have access to manuals)
