I would like to share the following macro I wrote for Tera Term, to be able to download hexfiles into P89V51RD2 from command line/batchfile (FlashMagic appears(-ed) to have problem with this, but frankly I did not investigate it in detail, maybe Andrew Ayre will comment).

Usage: ttpmacro.exe sendhex.ttl hexfile.hex [logfile.log]
Path shall be added to filenames where needed.

Comments welcome.
