Plate ) Newsgroups: comp.sys.apple Subject: Apple Kermit Keywords: found the missing 4 bytes Message-ID: <131@dicome.UUCP> Date: 15 Aug 88 21:57:23 GMT Organization: SERC * Dicomed, Inc., Burnsville, MN Lines: 19 A few days ago I posted an article descibing a "problem" I was having with my kermit ver. 3.73. Over the weekend, I discovered the answer to this. The first four bytes of a binary file are the loading address and the length of the file. Kermit expects these to be there already when it receives a file and saves it to a DOS 3.3 binary file. It also sends these bytes out with the data. It does make sense, since most of the binary data transferred to an Apple/kermit will be binary data from another Apple/kermit and will have these bytes. The stuff I was downloading, however, was YAMAHA DX7 system exclusive data and could have originated from any variety of PC that has MIDI. The way I got around this problem was to prepend the file with 4 "dummy" bytes on the vax side, download and then use a sector editor to change these bytes to the correct values. It was a lot to go through, but I did learn a few things. Thanks to those of you who took the time to reply, I would have mailed to you directly, but our mailer doesn't seem to be able to find you (old map). Doug Plate
