  Sliding windows Kermit has done this for a number of years. It's in
current DOS and UNIX versions and has been for about two years. Don't
know about other versions. It's in the current C-Kermit.

| o  32 bit CRC error checking.  I've never received a corrupted file
|    with Zmodem, unlike other froggy protocols.

  Kermit offers several error checking options, depending on your trade
between CPU and error checking.

| o  It is capable of dealing with brain-damaged modem servers that get
|    confused by control characters  (Ok, I'll admit, kermit *does* do
|    this too...)

  As you say...

  While I use and support zmodem, I have none of the complaints you
mentioned. They were all taken care of long ago. The restart feature of
zmodem is great, but it must be done at both ends, reducing the
usefulness of it in some circumstances, such as calling a BBS without an
option to try on the "continue" option.
