Hmm... just tried a DNet 'putfiles', Amiga to Sun 2/50, at 9600 baud (a direct connection). It transferred 114482 bytes in 128 seconds, gving an effective data rate of 894 bytes/second, or about 93% of theoretical maximum. (I agree... nice work Matt!). This was from VD0: to my home directory on the Sun. A DNet 'getfiles' of the same file yielded about the same (126.75 seconds). Out of curiousity, I tried a transfer both ways at the same time (with renamed files of course), and found the putfiles took 158.6 seconds, at which time the getfiles had transferred 61400 bytes (it was running at about half the speed of the putfiles all along). Taking the time for putfiles, and figuring the total line usage in both directions, it gives a total of (114482 + 61440) 175922 bytes transferred in 158.6 seconds, or about 1109 bytes/second. I am currently trying to write a version of 'tip' on the Sun that will allow me fully transparent access to the serial port. The reason is that I want to have the modem connected to the Sun, but accessable from the Amiga. Using the standard tip, I can do anything ASCII oriented, and use Aterm 7.3 connected to the Sun at 9600 bps (or baud.. :-) ), and it runs exactly the same as if I had dialled directly out the modem. I have my Sun source on both the Sun and Amiga, and do all my editing on the Amiga (with CEDPro). Whenever I change a module on the Amiga, I can simply type 'make', and the module(s) I changed get sent via putfiles to the source directory on the Sun. Typing 'make' in a DNet 'fterm' window then compiles the source on the Sun. (now all I need is rpc capability in DNet and I won't even have to have the fterm window up). -larry -- Van Roy's Law: An unbreakable toy is useful for breaking other toys. +----------------------------------------------------------------------+ | // Larry Phillips | | \X/ lphillips@lpami.wimsey.bc.ca or uunet!van-bc!lpami!lphillips | | COMPUSERVE: 76703,4322 | +----------------------------------------------------------------------+

>Larry, since you are running at 9600 baud, have you tried Dnet-nfs? No, I haven't. In looking at the files I have, I see only a few references to it. One was a comment by Matt about it, and contained a '(heh heh, just kidding :-))'. The other was from you, wishing you had it. :-) I would definitely like to play around with it though, especially if it allows me to do something resembling rpc. >Much nicer than getfiles/putfiles, IMHO.

The setup I have right now is pretty good. I had to make a bunch of empty files in the Amiga end and use 'touch' on them to fool the makefile into having some dependencies to work on, but when I type 'make', the directorty on the Sun is automatically (and quite quickly) updated. > Dnet-nfs isn't fully >implemented yet, and doesn't behave properly with some software.

Larry, since you are running at 9600 baud, have you tried Dnet-nfs? Much nicer than getfiles/putfiles, IMHO. You can edit your files with an Amiga editor from the mounted Sun directory. At 9600 baud, if the files aren't too large, it works pretty good. No need for getfiles or putfiles. In fact, I hardly ever use getfiles/putfiles anymore. On the other hand, if you are moving about between files, then this isn't such a good idea. Better to go back to an fterm. Dnet-nfs isn't fully implemented yet, and doesn't behave properly with some software. I can do loads & saves from the Manx 'Z' editor very nicely, but ProWrite/ProScript won't get or save files. :-( Browser and directory utilities are stable for viewing mounted directories, but will guru on some operations. Interestingly, Browser will copy smaller files ok but at somewhere above 50k files it will lock up just after writing the file - the file is copied ok, but you lose the machine doing it. While most shell operations are a bit slow, some file requesters such as the one in AudioMasterII can move about the mounted directories VERY quickly. Nice if your samples aren't too large. :^) The PCUtilities also work with Dnet's NF0:, and are really useable also at 9600 baud. Dnet-nfs also makes mail-checkers & print spoolers, etc. real easy to implement. Love that NF0: Thanks again, Matt. Kent Polk

It would be very expensive for me to call the bbs and get the stuff. Especially since anything above 300 baud is unlikely to succeed at all. >$16 per 10K hmmm. It is still expensive to make phone calls to North America, although the fee has dropeed substantially the last few years. So, its not ftp'able?
