file. If the end of file is encountered within a frame, the frame is
closed with a ZZZZCCCCRRRRCCCCEEEE data subpacket which does not elicit a response
except in case of error.
The sender sends a ZZZZEEEEOOOOFFFF header with the file ending offset equal to
the number of characters in the file. The receiver compares this
number with the number of characters received. If the receiver has
received all of the file, it closes the file. If the file close was
satisfactory, the receiver responds with ZZZZRRRRIIIINNNNIIIITTTT. If the receiver has
not received all the bytes of the file, the receiver ignores the ZEOF
because a new ZDATA is coming. If the receiver cannot properly close
the file, a ZZZZFFFFEEEERRRRRRRR header is sent.
After all files are processed, any further protocol
errors should not prevent the sending program from
returning with a success status.

6. If the ZMSPARS option is used, the receiver instead seeks to the
position given in the ZDATA header.

The sender closes the session with a ZZZZFFFFIIIINNNN header. The receiver
acknowledges this with its own ZZZZFFFFIIIINNNN header.
When the sender receives the acknowledging header, it sends two
characters, "OO" (Over and Out) and exits to the operating system or
application that invoked it. The receiver waits briefly for the "O"
characters, then exits whether they were received or not.

If the receiver is receiving data in streaming mode, the AAAAttttttttnnnn
sequence is executed to interrupt data transmission before the Cancel
sequence is sent. The Cancel sequence consists of eight CAN
characters and ten backspace characters. ZMODEM only requires five
Cancel characters, the other three are "insurance".
The trailing backspace characters attempt to erase the effects of the
CAN characters if they are received by a command interpreter.
