HP <--> PC ? Message #1 Posted by Kiyoshi Akima on 4 Apr 2006, 2:22 p.m. Many HP handhelds have RS-232 ports (albeit with nonstandard pinouts). Most new computers don't have RS-232 ports, only USB. Anybody have any good recommendations for connecting the two? I really don't want to have to copy stuff to a floppy, go to another computer, and then transfer from the floppy to the HP (and vice versa). Thanks. KA

Re: HP <--> PC ? Message #3 Posted by Kiyoshi Akima on 4 Apr 2006, 4:31 p.m., in response to message #2 by Thomas Radtke Do you or anyone else have any experience using such a converter with an HP handheld? Do they work well enough?

Re: HP <--> PC ? Message #4 Posted by Garth Wilson on 4 Apr 2006, 4:35 p.m., in response to message #3 by Kiyoshi Akima No experience to speak from here, but two companies I know of that make the interface converters are B&B Electronics www.bb-elec.com and Sealevel Systems www.sealevel.com .

Re: HP <--> PC ? Message #5 Posted by Han on 4 Apr 2006, 7:27 p.m., in response to message #4 by Garth Wilson Hi, I currently use Radio Shack's USB/DB9 converter. This one works under Windows XP and Linux. Under Windows, I can transfer files with my HP38G, HP48S/SX/G/G+/GX, and my HP95LX using Hyperterminal. Under Linux, I use CKermit. If you have any specific questions, feel free to ask. Han

Re: HP <--> PC ? Message #7 Posted by Thomas Radtke on 5 Apr 2006, 4:40 a.m., in response to message #3 by Kiyoshi Akima No, but what I've seen is one converter that _starts_ at 1200 Bit/s. I don't remember what the 48 series needs (and have currently no access to the manual) but that might be a problem. But that one was cheap, less than 5 EUR. Other converters I saw went up to 30EUR and more so this limit might not apply to these expensive models. Thomas

Re: HP <--> PC ? Message #8 Posted by Doug Wilder on 5 Apr 2006, 4:00 a.m., in response to message #2 by Thomas Radtke There are also PCI serial or serial+centronics boards for a few bucks. This one $14 but cheaper at a big box electronics store: http://www.buyextras.com/serialcards.html

82143 Printer Cable for HP41 for I/O Message #9 Posted by Philip on 7 Apr 2006, 9:38 p.m., in response to message #1 by Kiyoshi Akima I also have used the Radio Shack USB>Serial adapter on XP. It works just fine with my HP 200LX. I'm using the PC connectivity application for the 200LX, connecting the special 200LX to serial to the USB>Serial and all is well. It shows up as COM4: on my PC.
