A problem at this point may be that a AT-keyboard doesn't spit out ASCII but Scan-Codes, so a serial device spitting out ASCII would have to be put into the loop AFTER the stage that makes conversions, or you would have to convert ASCII back to Scan-Codes before. Btw. I'm not normaly into barcode-scanning, but for something at work i tried a USB-scanner (From Symbol AFAIR) to see what is stored in the barcodes that are on the prints that i have to generate. The scanner just registered as a plain HID-device, which resulted in the data comming as key-presses. It was just "Plug & Play", i didn't need any software or anything else. I just plugged the device in, opened a text-editor to catch the data, then i scanned the bar-codes and was happy. :-) So if you aren't nailed to a serial scanner, you just may try a USB-scanner. >>I recommend you take a look at sermouse.c >>in the drivers/input.mouse directory >>for a guide. > > > I looked, but the source code I have (2.6.17, Debian) doesn't have anything > called sermouse.c in the /drivers/input directory. # find /usr/src/linux-2.6.19 -name "*sermouse*" /usr/src/linux-2.6.19/drivers/input/mouse/sermouse.c Bis denn -- Real Programmers consider "what you see is what you get" to be just as bad a concept in Text Editors as it is in women.
