ZMODEM
<protocol> A file transfer protocol with error checking and crash recovery.
Developed by Chuck Forsberg.
Its transfer rate is similar to
YMODEM-g.
Like YMODEM-g, ZMODEM does not wait for positive acknowledgement after each block is sent, but rather sends blocks in rapid succession.
If a ZMODEM transfer is cancelled or interrupted for any reason, the transfer can be resurrected later and the previously transferred information need not be resent.
