Practically speaking, on a hardwired connection, what's the actual difference between Ymodem and Ymodem-G? Modern systems are sufficiently buffered so that disk access is near instantaneous. Have you benchmarked the two, say at 115Kbps full-duplex? I'd be interested in the results. I'm sending my MCU stuff using a hardware CRC computation over a USB connection configured as CDCACM full-speed.
Honestly, I'd like to know--I may convert to Ymodem-G if there's a significant performance improvement. I've tried USB MSD, but there's more overhead than just blasting out packets--and I don't care to expose the filesystem structure.
