We are considering an embedded processor that seems to use kermit
over its serial port to load its boot image. We can see the
ROM code that is doing this and standard practice is to use
a Unix Kermit on a workstation for the boot host.
Where can I find a short text description of the Kermit protocol
to see if this processor is really doing a kermit thing?
I looked at http://www.columbia.edu/kermit but only found the formal
specification in a postscript file. this appears to be a very fine
academic paper that is too formal for a quick read.
I have been told that this processor only loads binary files,
looks for 3 simple intro facts (where to load in memory, where to
begin execution, and how long is the load-image-file) followed
by the load-image-file-in-binary. It is further said that there
are no checksums or ack/nak stuff in the ROM code.
Can this be a valid (simple, minimal, whatever) kermit protocol?
Thanks for your help,
