I am using a third party product to create apps for mobile computers, ( Penright) , anyway in getting peripherals to work under DOS I have had to ask the manufacturers to send me the proper libraries and header files to make the barcode scanners work on their particular unit ( each one is different ) enclosed with the email from the company is this "There is a bar code example under the barscan directory. It links
with libraries touch_s and periphs for small memory model. You would
probably only need to link with periphl for large model to integrate it into
your Penright application." As I said I am a complete newbie at this, can someone explain what these memory model terms mean? In laymans terms also if possible.
