Thank you for the info Curtis.
I get the message:
 waiting for '>'
ERROR!!! Expected '>' but found '<'

Unless I change the boot.s file from:
.org    2048    @ ensures the file is 2k in size. (no more, no less)

to
.org    2040    @ 

and recompile....

Then I get:
000000000000000000000000000000000000000000000000boot.bin: Success

***Exiting***
***********************

I really do not know how Success shows up(must be sent from the TS7000 )
because entering:
linux:/usr/local/opt/sb # find /usr/local/opt/sb -type f -print |xargs
grep -n "Success"
linux:/usr/local/opt/sb #

yields nothing.... from serialblaster.c or any of the other support
files...

I can only guess that the ts7000 responded with a Success due to file
transfer.... unfortunately nothing else happens -- it never gets to the:
waiting for '>'
found '>'

so it does not go to the next function of serial blaster code which as
you know is 
1.open the bootloader
2.wait for length acknowlegement
3.send redboot.bin
4. execute redboot...

obviously something is not going correctly so I am left with taking
the messages received and try to make sense of them-which in this case
will take me some time, but with help I hope it is possible... 

This kind of troubleshooting can frustrate me but I find the
application very worthy of looking into at great depth, for my own sake..
I feel lucky that such an interesting application is even offered as
open source...
If I get it to work, I will feel more at ease in being dangerous with
commands I do not know much about... and will want to get another
model ts7xxx to mess around with....
