Description gonglinglei 2018-02-05 08:27:46 UTC

1. zmodem upload implement read the whole file into memory at one time cause OOM
2. got ERROR Retry 0: Got ZCAN, Chances are the pty/tty on one of the systems are not 8-bit clean.  (Linux is 8-bit clean, NetBSD is not).

For zmodem transfers, do not read entire file into memory

Read at most 1Mb of data instead of loading entire file into memory.
Add -e to force sender to escape all control characters
