- The Zmodem implementations in some programs are incompatible with each
- other. Old Zmodems only work with 1K packets, so the new ones that
- support larger ones are supposed to start with 1K, then try 2K, 4K and 8K
- after awhile, dropping back if the larger packetsize doesn't work, but
- some implementations will try the larger packet size again, giving you
- more errors. Setting the window size to 2048 makes it use 2048 byte
- packets. -w 1024 will probably get rid of ALL the CRC errors.
