Angry how to transfer data via ymodem with sb?

So i have an embedded device that is in u-boot and i need to load an operasting system on it (proprietry real-time os) i can do this via ymodem by the following steps.

1) Prepare device: uboot> loady
2) in minicom send via ymodem and select my file.

now this works. but i want to do it outside of minicom so i can put it into a shell script as it is something i am going to be doing frequently and i already have a script for steps of the process up to this.

so my research tells me that minicom uses the program sb(sz) to do this but i cannot figure out how to use it.

sb --ymodem -by <filename>.img
which should tell it rb(rz) to expect binary data and overwrite the data.

there are alot of different possible arguments but none that i thought would help!

Hope I have explained myself clearly

Ahh i didnt realise i was posting this in linux newbie. (shows im a noob ahahah)

Could a moderator please move this to an appropriate place where it may receive the right attention!


Edit: Best place would be the embedded linux section probably as they are the people that will most likely be using this tool!

Ymodem is such an odd file transfer implementation. Perhaps you can accomplish the scriptability (yup, that's a word; I just invented it) part by using C-Kermit, which is itself highly scriptable, rather than minicom.
