Easily scriptable. The simple task of resumable transfers is so automatic,
I don't really consider it scripting. More like a batch file.
The automatic compression is not intense. I wouldn't compare it to
zip/unzip. When I was transferring a 20-30MB file on a 14400 line,
I made zip/unzip part of the script at each end.
Unattended? I never noticed the kermit part of the process at all. The
batch job that created the file at one end invoked kermit as its final
step. At the other end, when the file appeared, it was processed. At
one end, the guy would load a tape on a PC-based tape reader, and walk
out the door for the evening as soon as the zip started. His only concern
was a good tape read. At the other end, it just fell in to the process
flow... no one noticed when.
I've used Kermit on AIX, Solaris, Linux, DOS and Windows95+
interchangeably, with perfect interoperability.
