Hi Ralph, (...) There is present automatic detection in XMODEM protocol group (they are three XMODEM, XMODEM/CRC and XMODEM-1k). But difference comparing to YMODEM and ZMODEM is bigger. Simply because XMODEM transfers only a raw data, but YMODEM and (...) (25 years ago, 14-Nov-99, to lugnet.robotics.rcx.pbforth)

| | Save image in pbForth (without any save-supporting code)
|

Hi Ralph, It appears to be a quite easy task - to save the pbForth image without SAVE- SYSTEM support. Only thing you need to do is to define a marker before you will upload the “save” words: MARKER end_of_image [ upload SAVE-SYSTEM support ] After (...)

Sergey, (...) Never mind my last message. I can see you store the actual task chain in the definition of MARKER and then restore the task chain correctly. WOW! I think pbForth is on the cusp of respectability now! Cheers, Ralph Hempel - P.Eng (...) (25 years ago, 14-Nov-99, to lugnet.robotics.rcx.pbforth)

(...) WOW! This is great Sergey! I haven't had a close look, but are you actually taking ALL of the tasks out of the list, or just the ones defined AFTER the point in the dictionary that is being restored by MARKER ? (...) Thanks for the kind words. (...) (25 years ago, 14-Nov-99, to lugnet.robotics.rcx.pbforth)

| | Multitasker and MARKER word
|

Hi Ralph, Here are my results regarding MARKER and multitasker problem: small additional code in MARKER word could do the trick. It was even easier then I though: you don’t need to put tasks in the “sleep” mode. Just remove them from the task chain (...) (25 years ago, 14-Nov-99, to lugnet.robotics.rcx.pbforth)

Sergey, I'll add the other basic wordlist stuff to the kernel, then I'll let the users "build" the optional system to their needs. In fact, I have three extra files that I assemble into a complete kernel. The RCX definitions (all assembler) (...) (25 years ago, 13-Nov-99, to lugnet.robotics.rcx.pbforth)

Hi Ralph, (...) Well, I meant that I know how to do it, but not yet tried ;) Also, it shouldn't be so difficult, so I will try it now. (...)

I think a SAVE_SYSTEM script that is loaded in just before the system is to be saved is right. I (...) (25 years ago, 12-Nov-99, to lugnet.robotics.rcx.pbforth)
