Either keyboard or serial. Assuming suitable software, serial may actually be simpler for the scenario jy-p suggested... >>> the application is inventory tracking, etc, where several users would >>> concurrently scan and have barcodes register with a single machine. If it's keyboard (bthid), there was a post on misc@ fairly recently with details about making a bluetooth keyboard work, it may be useful.
Re: wireless barcode scanners
all of the barcode scanners I've ran across simply show up as keyboads, and insert text just as if you typed it out. no need for drivers at all. I would wager that the bluetooth models also attach as a keyboard.

These are typically not SCSI devices (none that I know of are, at least), they are typically Serial, PS/2, or USB HID devices. I was reading that discussion on the SANE developer list. The list is 8 years old. I think somebody even mention there that bar code scanner can be attached as PS/2 thing. I thought I had seen something about SCSI bar code readers but I am probably mistaken. All they do is translate the barcode scanned into ASCII for processing by some application. I think that what my third link about "hardware solution" was saying. Are there such applications written for OpenBSD and what do they actually do? Some newer scanners use Bluetooth, but there are also cordless scanners that talk to a base station that translates the wireless signal into serial, PS/2 or USB input I can say with 100% certainty (I have one in front of me, ATM) that the Symbol LS1203 works with no problems with OpenBSD. Here is what dmesg reports when I attach the scanner. uhidev1 at uhub4 port 1 configuration 1 interface 0 "?Symbol Technologies, Inc, 2002 Symbol Bar Code Scanner" rev 2.00/2.01 addr 2 uhidev1: iclass 3/1 ukbd1 at uhidev1: 8 modifier keys, 6 key codes, country code 33 wskbd2 at ukbd1 mux 1 wskbd2: connecting to wsdisplay0 As you can see, there is no SCSI black magic or any proprietary voodoo going on here. The scanner is simply detected as a USB keyboard, and acts just like one in my day to day use of it. Tim Donahue Thanks for the dmesg and for teaching me something new.
