    RE: Which terminal on Linux? plus random thoughts. —Ralph Hempel
   (...) I have beta quality Tcl code that sends an SRECORD firmware imge up to the RCX (fast or slow) and has basic terminal capabilities. It also strips comments and whitespace out of files as they are uploaded to reduce the time. I'd like to put a (...) (24 years ago, 4-May-00, to lugnet.robotics.rcx.pbforth)
   
        Re: Which terminal on Linux? plus random thoughts. —Steven J. Morris
   (...) I missed that. What do you mean by simply covered. (...) No surprise there. I implemented XMODEM a long time ago on a spectrometer. I don't remember the details but obviously it stayed with me. Besides all protocols tend to look the same at (...) (24 years ago, 4-May-00, to lugnet.robotics.rcx.pbforth)
   
        RE: Which terminal on Linux? plus random thoughts. —Ralph Hempel
   (...) Umm, I mean cover the tower and the RCX with a box.... :-) (...) No, Ernst's idea has a preamble byte for the transfer, and then the RCX grabs all of the chars and sums them. If the sum is wrong, then it NAKs the packet and the host sends it (...) (24 years ago, 4-May-00, to lugnet.robotics.rcx.pbforth)
   
        How much RAM is left? —Steven J. Morris
   (...) I believe that. 32k of RAM is a luxury for forth. That's another thing people don't generally understand about forth, they way it effectively compresses runtime software. I've heard of ram reductions of a factor of 5-10 for forth when compared (...) (24 years ago, 5-May-00, to lugnet.robotics.rcx.pbforth)
   
        RE: How much RAM is left? —Ralph Hempel
     (...) Nope, the memory is allocated linearly from the end of the image. The current image size is 12 or 13K. New dictionary entries and ALLOTed memory are interspersed as they occur. NOTE WELL that there is a subtle bug in the RCX ROM routines when (...) (24 years ago, 5-May-00, to lugnet.robotics.rcx.pbforth)
   
        Re: How much RAM is left? —Ernst de Ridder
   (...) Pfff. As if that could possibly be important. If it isn't an object-oriented client-server architecture in Java++, it can't be serious :-) (...) If I read the source correctly, memory is allocated sequentially, and in my image I've got SOURCE (...) (24 years ago, 5-May-00, to lugnet.robotics.rcx.pbforth)
