Hello there Alex ....
AM> Hi Randall,

AM>> like bull to me too, but when both ends report it, I believe it.
AM>> I

I'd suggest glasses and a new timepiece!

AM>> also timed it using my watch, at 3300cps it'll do 1000000
AM>> bytes in 4:58, it was below 4 minutes when it reached 1,000,000
AM>> bytes, and I trust my watch. Telix also reported the same thing.
AM>> The file was 1.6MB.
RL>> It's impossible, Alex. It's that simple.
AM> A 33.6K modem can pump 4000 cps, and 56.6K modems work on
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Under sterile conditions that is possibly achievable. (Bill..Russell??)
Still a long way short of 4290 tho'.
BTW what's 56.6K modems have to do with this??
AM> standard lines (I think), it's the terminal that slows the
AM> transfer down. Perhaps the terminal I go through is one of the
There is a theoretical maximum that is achievable at this speed. Your
4290cps is way beyond this and is not possible.
AM> new ones, my lines could be very good. Besides, I think that for
They'd have to be better than "very good", they'd have to be cable. :=)
AM> the 33.6K modems they just use the same chipset as in the 28.8
AM> and modify the BIOS.
So what's the point here??
AM>>> end it reported 4290 cps average. What do you think?
Still incorrect.
AM>>> This modem is a Netcomm Roadster V34, and the highest CPS rate
AM>>> I ever got before was 3390 cps in the same situation as above.
RL>>> ^^^^^
AM>
AM>> Why did you highlight the before bit? I changed nothing,
AM>> and it was definitely a ZIP file. Why don't you try the BBS?
AM>> It's called Stargate and it's in Melbourne, don't have the
AM>> number on hand but it's in the VIC BBS listing.
RL>> What for? The 4290cps is pure nonsense.
AM> Got 3500 cps on my last upload. These files are definitely
I won't argue that!
AM> ZIP files because I compressed them myself with the -EX switch.
I wont argue this either.
RL>>> Even that is good for a Roadster. The 4290 is not even
RL>>> remotely possible giving your example above.
AM> Well, I uploads about 10% faster than it downloads usually.
AM>> Hey, 3390 is good for any modem. In a magazine I read, the
RL>> Magazine articles rarely generate "real time" operations
RL>> in their tests. In the field the Roadster is an average
RL>> performer.
AM> So how fast does your modem go? Whether it's 8 BIT or not,
AM> it'll still go the maximum symbol rate allowed on a standard
AM> phone line, and it has done so.
Nowhere near 4290cps.
