- Older versions of Kermit were very slow in file transfers.
- The newer versions (>3.1) are much better. In my tests, it runs
- at least 90% of the zmodem speed. However, for text files, the
- zmodem compress option (-B) gives zmodem a clear advantage.
- However, zmodem is much more vulnerable to line noise.
- Our lines are often noisy; zmodem gets what it thinks is an
- abort signal and drops the line. Kermit's quit-and-go-home
- signal is longer, or something, as it almost never gets fooled
- by line noise.
- I often collect several files and then start the download
- (~0400) just before I go to bed. This is rarely successful with
- zmodem, while kermit almost always succeeds.
- On the other hand, zmodem has a restart capability that
- will complete a partial file.
- So, for short, esp ascii files, use zmodem. For long
- unattended transfers, use Kermit.
