I just realized that the sync button on the cradle defaults to usb/serial even though i set up a super fast usb configuration. The new config only works if i manually select it and then WHOA! fast fast fast.

How can i change the default button on the cradle?

I had to create one manually. I then edited it to use the highest transfer (200k+) possible. Seems to work.

DANG! is that fast!

When I first got my Visor, I made a USB connection,n but I never saw the speed options.. o I'm going at 200k a second!

I'm glad somebody is discussing this. A week ago I asked HS tech support what settings I should use in the Hotsync app on my Prism, and learned 1) that the tech support reps don't have access to OS 3.5 (they can only access a VDx), so they couldn't tell me anything and 2) when I tried getting an answer by email, I was told "just set the sync speed to 115200 on your desktop hotsync manager. The Prism will know what to do." Yeah, sure it will.

Can anybody give me guidelines on how to set the options on the hotsync app? If this is covered in the Prism manual, I sure haven't been able to find it. I sync to two desktops - a Win95 with a serial cradle and a Win98 with USB. I noticed tonight after syncing to the Win98 machine that my "connection method" (reached through HotSync - Options/Connection Setup - Direct USB/Serial - Edit) has somehow been reset to Serial to PC, with a speed of 57600. I assume that means that it's actually been syncing at that speed rather than USB max speed. Any help is appreciated!

Go into the Prefs application and you can edit or create your own new connections under the connection category. Simply create a new connection and set it as USB to PC, then you can max out the transfer rate at like 200k. When you go to HotSynch, you'll have to change the connection method when you move from one PC to another, and its simply a pull down menu below the large HotSynch button in the HotSynch app.

I opened up Hot sync on the prism. Went to connection setup. Opened "new". Named it "Custom". Chose "USB to PC". Went to "Details". Chose "230400" speed. Left flow control on "Automatic". And saved it all.

Now do I need to do anything more to it?

And how do I monitor to see if the speed of the sync is any faster?

you will notice the increase in speed immediately.
but it only works for me when i manually select the higher speed and touch the screen. The button on the cradle always reverts back to the slower setup called usb/serial.

I did exactly what JSchaff did and then synced, and it certainly seemed to be running very fast. But when I checked the HotSync app after syncing by going to Connection Setup-Edit, I discovered that the "connection method" had reset itself to USB/Serial to PC. Like JSchaff, I had chosen USB to PC. When I go on to "details," it still is set for 230,400 bps with automatic flow control. (That's USB speed, right?) Why does it reset itself to USB/Serial when at that point I haven't done a serial sync?

When I synced this AM to my Win95/serial machine, I didn't change anything on the hotsync app, and the sync went fine. Strangely, when I get into "details" in the hotsync app, speed is still listed as 230,400 with automatic flow control. But surely my lumbering Win95/serial setup is not syncing at that speed, is it?

When I posed the question that I outlined in my first post above to HS tech support (by email), I got this reply:

"You do not have to worry about the speed set to 57600 as this affect on the Hotsync done with the serial cradle the best speed recommended for the serial cradle is 9600. The USB hotsync does not depend upon the speed set in the Connection setup. So the Serial Hotsync will follow the
Speed setup but the USB will always work at the Optimized Best speed."

Now, I don't have a technical background, but I like to think of myself as being a fairly smart person. But I just don't get it. Does anyone here know what HS is trying to say?

Does this really mean that a serial hotsync runs at 9600 bps? I thought it ran at 57600. I also thought that one of the supposed improvements offered by Palm OS 3.3 over 3.0 was that serial hotsync speeds had been improved to 115,200 bps. I also kind of guessed that USB syncs run at 230,400. Do I just have my facts all wrong here?

I think we're missing the point of the original question...

I too have created a "Direct USB" connection at 230K, however this connection only gets used if I TAP THE HOTSYNC ICON. It NEVER gets used if the hotsync button on the cradle is pushed - the default "Direct USB/Serial" connection is used. It seems the Hotsync app is hardwired to that connection if the cradle button is pushed.

Yes, my custom connection is selected in the drop down under the hotsync icon.

I don't think the speed has any meaning when set to USB.. USB has 2 fixed speeds. (slow 1.5mb/sec & fast 10mb/sec (bits not bytes)).. USB ISN'T rs-232 serial..!! (don't be confused by the word "serial" in Universal "Serial" Bus.. it's a very different beast.

I think the speed setting is only there for true RS-232 serial connections.. Under USB it most likely has no affect.,

So I guess the question we're all trying to ask is how do we maximize sync speed when we use 1) a Win98+/USB connection, 2) a Win95/serial connection, and 3) switch between both? Is there any value in making a custom connection setting? If not, why does the option exist?

USB on win98/2000 will be the fastest of all choices.. I don't believe there is any way to change the "speed" and make it any faster than it already is, also it is fixed at it's speed..

On win95/serial, I'd set the "speed" setting as high as your computer's UART Chip (the serial controller) will handle with out errors.. (note: it is possible to set it too fast, you'll get lots of errors)

I'd have to explore the custom setting.. there may be conditions you would want to define your own, I can't think of any at the moment. Maybe IR hot sync?, network hot sync? Old/slow UART serial port?

EricG - thanks. On my Win95/serial setup, I created a custom connection (called "serial only") and set the sync speed to 230,400 bps, and it syncs fine. But surely it can't be running at that speed, can it? I thought serial connections topped out at 57,600 (or maybe 115,200).

Some of the (mostly common now) newer chips that control the serial port can go that high (115 to 230.4 I think might be MIDI (digital musical instrument) speeds)... 33.6KB, 57.6kb etc. is usually in reference to modem communication speeds, which also use the serial connector but have to convert the digital data to analog sounds and back again over the phone line, this obviously slows things down quite a bit, but in your case, you are talking about a "direct connection" between the Visor and the computer, so you can go higher as there is no "modem" involved between your Visor and the serial port on your computer.

Ironically the "wire" between your (external) modem and your PC might actually be operating at 115kb (or higher), however, because of the digital to analog , analog to digital conversion limitations, because of this bottle neck, you won't see the overall performance go beyond 56kbs, it just means that the computer can "talk to" the modem quicker (and vice versa). Internal modems work somewhat the same way, but the "wire" I am talking about is "built in" so it's harder to visualize.
