Holy moley! I just tried the new version of NComm, and boy, am I amazed! It has built in XPR transmission protocals and are they fast! I downloaded off of a 19.2k direct connect fiber-optic network with both JRCOMM1.01 and Ncomm1.92 to see which was faster. To my amazment Ncomm transferred around 1850 cps whereas jrcomm hit around 1550 cps. I didn't believe my results so I downloaded another 300k file to test again. Sure enough, it peaked out at 1850 again! I didn't believe it again, so I figured out the CPS via my calculator. Te average CPS over the entire transfer was jrcomm1.01 1565 CPS and ncomm1.92 1849! How can an external packet/library format such as XPR beat an inline optimized zmodem code that jrcomm has?

Silly me. Forgot to turn off my escape ctrl characters. I did my download testing on my new account on a Mac II (a system on our network that doesnt need escape expansion). Ncomm1.92 doesn't have escape ctrl chars so I totall forgot about it. Well anyway, Jrcomm1.01 is still the fastest zmodem program. Downloading a couple big files produced an average CPS of 1850-1860, which is right in line with Ncomm. I'm still wondering though, how an external protocal could be so fast!

Where is NCOMM 1.92 available? Also along this vein, is there a way to select batch uploads on NCOMM 1.9? I've tried and tried everything I know to selevt more than one file, to no avail....If there is no way, is it fixed in 1.92? I like the scripts, but if JRCOMM add AREXX, I guess I'll have to register (what the hell, it's only money....guess I'll do it right now) ----Roy suttonrv@vuctrvax cs275rs@vuse.vandebilt.edu

My roomate usually gets 1864 cps with JrComm 1.01, and I get about the same with most of my terminal programs, whether I use zmodem or ymodem. > >How can an external packet/library format such as XPR beat an inline >optimized zmodem code that jrcomm has? > >Phil Dietz > >BTW, Ncomm1.92 has added the rest of the Zmodem flags so it's usuable now. > > >-- Subliminal Signature > Phil Dietz > A M I G A 231b3678@fergvax.unl.edu > Univ. of Nebraska -- David Tiberio SUNY Stony Brook 2-3481 AMIGA DDD-MEN Tomas Arce Any students from SUNY Oswego?

You obviously had something setup wrong because a download is *entirely* dependent on the sender, you can only recieve file as fast as it is sent. Off hand, the three things that kill a JR-Comm transfer are the space check, file saver and XON/XOFF handshake options. Willing to bet that you had one or more of these active, did you? BTW, I checked out 1.92 myself, it still can't upload (which is the benchmark for any FTP) as fast as JR-Comm. -jack-
