I'm curious to know how/why you opted for your message not to be archived on this forum? Ancient history... Many moons ago, most Usenet servers expired posts on some regular schedule (text groups may have gone a month to a year depending on traffic; some of the heavier binary image groups expired in less than three days -- miss a day and you might really miss a day worth of traffic). Then came Google with their "archive for the ages"... No chance to have the world forget things one had posted... Shortly thereafter the extension header x-noarchive was implemented. I chose to have my client embed that header. > >Unfortunately I don't have any assembler experience. It strikes me as even more hairy than C! Something left to those forced to do it under duress or the few for whom this excites. If I had to ever programme in Assembler I would want to keep it to the absolute, absolute minimum. Dare I ask you to recommended some learning materials? > Unfortunately, it tends to be specific to the processor chip -- I'm presently going through a book on the ARM Cortex-M (and while the R in ARM started life as RISC, it looks like CISC instruction set compared to my college mainframe in the 70s); I have a book a few books on PIC chips lying around, and maybe one on AVR). I don't even want to think about modern CISC processors. The old Blacksburg "Bug" books are obsolete if one could find them... However, if you really need responsive device drivers, you'll probably end up in assembly at some stage; there are things that not even low-level C allows easy access to... -- Wulfraed Dennis Lee Bieber AF6VN wlfraed@ix.netcom.com HTTP://wlfraed.home.netcom.com/
