Setting up minicom and ckermit for u-boot serial file transfers

Took awhile to get this simple bit of legacy working. I'm working over a USB serial console to a dev board and needed to update some parts of flash but I don't have working ethernet yet. U-Boot allows for kermit binary file transfers, but default ckermit settings don't appear to work well. So to speed others along, here's what I did. Quite simply, add this to (or create) ~/.kermrc:

set carrier-watch off
set handshake none
set flow-control none
robust
set file type bin
set rec pack 1000
set send pack 1000
set window 5

Otherwise, ckermit expects some modem line signals and CONNECT before it starts the transfer. Now you can use minicom's send command.
