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. I guess I'll have to get the mazewalker words cleaned up
so I can post them without shame.
On the XMODEM side, I think that even a ZMODEM program will "fall back"
to XMODEM. Is this true? I'd really like to use CRT for evrything under Win9x
because it even has a "keepalive" string I can send to the RCX. I'll
have to play a bit.
Finally, what do you vote for in terms of a minimal system? I was thinking of
tearing almost everything optional out of the kernel and only using about 30
core words, since that's all most folks ever use in an application.
I'll have to check and see how the words are cross-referenced to see how minimal
I can make it all.

| 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)
