- And just what do you think YMODEM-g is? It is also a streaming protocol.
-
- It's also got overhead that's five orders of magnitude less than ZMODEM for
- averagely distributed data profiles, better if the profile is unfriendly to
- the ZMODEM protocol.
-
- YMODEM-g also protects it's data packets with CRC, so if an error does
- occur due to the modem/computer electrical connection (slim if you're not
- using cheesey cables and connectors), the transfer will abort, so what?
-
- So long as you're not using some totalitarian program, it should be
- saving aborted files for you so that you can recover the remaining portion
- with ZMODEM resume.
-
- If you're using a fast modem with error correction and have quality cables
- YMODEM-g is a very efficient alternative.
