Tried to write a config.ini in "/empeg/var/", but even using the rw script, that area was still read only. I got this path from the development site, is it
correct? i.e. /empeg/var/config.ini ??

/empeg/var is on the music partition so you need to use rwm and rom.

Also, the baud rate verbs that you've embedded, are they like 9600, 115200 or 115K?

Simple numbers like 115200 and 9600.
