1) When I transfer files from ProDOS (with an II+ and an 7710 serial card) to our host using Kermit 3.84 (last version from APPLE2-L) using an 8-bit connection (i.e. no parity on both sides) the Apple Kermit sends the control prefix (#, $23) with the high bit set so that the receiving side won't be able to convert back control chars which makes unrecoverable trash out of the file. Has anybody else similar problems ? Does somebody know a fix ? (Currently I just limit the Apple to space parity so only seven bits can be transmitted. This can't be used, of course, for binary files !) 2) Does somebody have the GS version mentioned in the deARC //e docs posted recently on the binary lists ? 3) I remember a lot of talk about save (gateway proved) 6-bit coding sheemes back in May. Are there any results by now ? 4) While I'm on the subject of saving net bandwidth: When distributing ProDOS 16 (oops, GS/OS) software (to be more specific: OMF files), it should be ensured that they are in the shortest V2 format by applying the COMPACT utility from APW. Free Term GS, for example, will go down from 63488 to 44838 bytes, a reduction by 29% ! Of course, this is directed more to programmers. (I've even seen commercial programs which I could back up from two onto one disk with the help of COMPACT !) ______________________________________________________________________________ M a t t h i a s K a p f f e r mail : Hermann Brill-Strasse 10 D-6200 Wiesbaden West Germany phone: +49 6121 460854 email: BITNET : KAPFFER@DMZRZU71

How can I gain the use of this utility? UUCP: {rosevax, crash}!orbit!pnet51!shawn INET: shawn@pnet51.cts.com

Stick to BLU until something like > "BLU GS" comes out... COMPACT doesn't compare to BLU: COMPACT will be applied once on the sending side (or even better the programmer's side); the resulting OMF load file will still execute (if the System Loader isn't too old) without any additional action on the receiver's side (as contrary to BLU or SQUEEZE) because COMPACT only transforms the relocation dictionary to a more compact [a quick quiz: where does it's name come from ?] form by specializing on certain record types (like the ones for two byte addresses which don't include the redundant zero bank byte) and storing relative addresses in the corresponding holes left in the load image. That leads to reduced disk space requirements and faster load times. Therefore COMPACT is independant of BLU (and not a replacement) and can *always* be used before squeezing and bunnying OMF files together. > fadden@zen.berkeley.edu [crashed] > c60c-3aw@widow.berkeley.edu (Andy McFadden) ______________________________________________________________________________ M a t t h i a s K a p f f e r mail : Hermann Brill-Strasse 10 D-6200 Wiesbaden West Germany phone: +49 6121 460854 email: BITNET : KAPFFER@DMZRZU71
