ms dos 9x

this should probably go in the hardware-embedded forum.

your question still isnt clear... are you trying to read from parallel, serial or usb port ?

if you are trying to read from parallel port then i think you would need to cat/ hexedit/ od by reading /dev/lp* or /dev/parport*

And it's not at all like the DOS command line, it's much more powerful. And unlike in Windows, where the command line is considered a relic of the past that's to be avoided, in Linuxtha it's considered just another interface that's better suited to some tasks than a GUI.

thanks very much. i have the site bookmarked. that was probably what i was asking for.
cheers and thanks

I do not see anything in that mission-statement which "necessarily requires" the use of Linux at all; nor, particularly, the use of "that old computer."
Electrical engineers all around the world are "re-programming EEPROMs" just like yours, and none of them are scratch-building the tools with which to do it. They selected existing, well-tested software that does the job, and then they bought the computers with which to do it. So, you really are not "boldly going where no man has gone before," and you should not take that approach.
You should fully expect the Windows-9x tool to be useless in modern environments, no matter what environment it is, because computers now have (and, operating systems now enforce) hardware protections against the arbitrary use of system resources. Software drivers must be used. Windows 9X (and MS-DOS) had no concept of such things. Nevertheless... this is not an issue that you need to address. The developers of the software tools that you need to merely select and buy have already done all of these things for you.

It is merely a waste of time to do a thing that has already been done, or to bash your head against the obstacle of "the first approach that popped into your head" (when a wide-open window is right next door to it, and you simply haven't bothered to look around first.)

We have all done just that, of course ...

i am sorry, i didnt want to offend you. i will be honest, the fact that linux is free is what attracted my attention. that fact that you could have full acccess to "softawre" (if you know what you are doing) is what grabbed me.
i do purchase equipment etc, as its needed. it was something to learn,play with as learning linux.
thank you for replying.
