- HyperTerminal. A fine piece of software from the early 90's.
IMHO it is not good software (to be honest).
I remember (from another forum) many problems and complaints from people using Hypertermnial for communication with AVRs.


- redboot ymodem routines. Do the ymodem redboot routines have
difficulties recovering from a period of silence/errors?
There are some timeouts coded inside so it depends how long/many silence/errors you encounter. Eg. I started loading ELF image then decided to stop transfer and it takes over 30 seconds before redboot give up and display "prompt".
I also found (not much investigation) that redboot running from ROM (on EB40A) is not capable to transfer at higher speed than 56kbs.
