Re: [ECOS] Redboot: "load -m xmodem" command

["Mike A" <embeddedeng at hotmail dot com>]

Hi Gary,

Thanks for the info.

My time measurements on Window Hyperterminal:
It printed "CCCCCCCCC", 11 characters in 30 seconds. So, it has 3 seconds 
inter-character gap approximatly. Which I think is pretty ok from what you 
said in the eariler email.

Are you developing on Windows?? If so, what terminal program are you running 
this on? Let me know what you think about this.

Thanks a lot,
-Mike.

RedBoot> load -m xm
