Fun times. My first experience with modem file downloads was the ASCII Express protocol on my old Apple //. Cutting my teeth on modem init strings, and keeping current with file protocols helped me break into IT despite not having a degree in it.
For example: "What, your Xmodem transfer always fails on the same block... oh, you most have xon/xoff flow control turned on. Try swapping that &K4 with an &K3 instead."
At one wacky point in my career, I ended up supporting a program "SPC" (software protocol converter), that flipped zmodem over an X.25 network to SNA to a mainframe. It ran on an OS2/Warp box. I wish I was making that up. I really do.
