And speaking of kermit... I believe I have run into a bug in the kermit protocol. This bug manifests itself when transfering 'ARCed' files. For those who don't use micros, this is a method to compress one or several files into and 'archive'. The archive software uses several different methods of compression depending on what the data looks like. Anyway, obviously these archives contain binary data. I have been using kermit (binary mode of course) to transfer these archives. Now here is the problem: About one file in twenty kermit corrupts! I have tried using several different versions of kermit on several different machines and have seen the same results. I am using an Amiga 1000 computer. I have tried the 'official' kermit release,and several PD software packages with kermit. I have talked to several different brands of micros running several defferent versions of kermit. Also several larger systems including VAXEN and Perkin Elmer machines. Has anyone else seen this problem? Is there a string in the archives that is fooling the kermit protocol? I just don't understand what is happening... As of late I have started using XMODEM-CRC whenever kermit trashes a file and it will xfer it just fine.... Chris Schuermann Oklahoma State Univ.

In article <3627@okstate.UUCP> chris@a.cs.okstate.edu (Chris Schuermann) writes of a problem that he's been having with a number of kermit implementations. The problem manifests when trying to transfer a binary file (in his (her?) case it was ARCed files). There is a problem in earlier releases of C-Kermit (at least) where a binary transfer would occasionally go awry. Check the okstate kermit archives for more info. (Sorry, I don't have it). BTW, I've never seen this problem myself even when I used the C-Kermit modules that supposedly had the problem. >Chris Schuermann >Oklahoma State Univ.
