Hello,
first of all, i'll have to say, that i'm very glad to have a FORTH on
the RCX but, and the but is a big one, there are some problems if you
want to develop some even small pieces of code.
First of all, the downloading of source is very boring. It remembers me
to the good old day, when we can have a coffee break when starting a
compiler. The infrared link is very unreliable for me. I have to set a
line delay of 100 ms and a character delay of 80 ms (really) and even
with this delays, it is not guarantied, that the source is transmitted
correctly. This heavily removes the fun from programming little robots.
I have tested the link under several conditions, but nothing seams to
help. I think, there should be a implementation of LOAD, for the RCX,
which implements a reliable download of source to the RCX (YMODEM?
ZMODEM?).
This is the link to the second point. I can't get the SAVE-SYSTEM word
to upload the SRECs to the host. Has any one experiences with
SAVE-SYSTEM an 'rx' under UNIX?
I'm working with Linux and 'cu' to connect to the RCX and 'ascii-xfer'
to transfer sources to the RCX.
Regards Carsten Müller

| Hi Carsten, Nice to see an interest to the subject (even not so cheerful ;) Ok, first question, you are right, it's quite boring. But this is the price for "power". I believe that only direct byte-code uploading will be faster. My only suggestion - (...) (25 years ago, 14-Dec-99, to lugnet.robotics.rcx.pbforth)

| (...) Yes, you are right. I have the char delay to about 10 or 20 msec and the line delay at 100msec. Remember that your monitor and other IR sources may interfere with comms to the RCX. Try fresh batteries and put the bot and tower under a box... I (...) (25 years ago, 14-Dec-99, to lugnet.robotics.rcx.pbforth)

| (...) Ok yesterday evening i tryed to track down this problem. Using a y cable and my old terminal. The communication starts normaly. The first frame was transmitted correct, 'rx' answered with <ACK> but the RCX never sees the <ACK>. If i type the (...) (25 years ago, 15-Dec-99, to lugnet.robotics.rcx.pbforth)
