Using File Transfer Programs
3-22
Falcon
®
DOS Portable Terminals
The
O3
setting is unique in that it causes the transferred file (binary or ASCII)
to be appended to the end of the old file rather than overwriting it.
With Zmodem, the
O
option can be used with the
C
option setting for crash
recovery (refer to
). If
C2
(follow sender) is specified on the command
line, then the receiver will use the sender’s crash and overwrite options. Any
options local to the receiver will be ignored.
Q
Quiet Mode:
This option toggles quiet mode. When quiet mode is enabled,
minimal information is displayed about the file transfer in progress. Generally,
only the name of the file being transmitted is displayed. When not in quiet
mode, XFER will display a copyright message, the filename, and file statistics,
including a running count of bytes transferred.
Running XFER in quiet mode on the Falcon can significantly improve serial-
transfer performance, especially at high speeds. At 115200 baud, transfers are
four times faster if quiet mode is enabled on the Falcon than if it is disabled,
owing to the delay inherent to writing a running byte count to the screen.
Since the
Q
option is a toggle switch, each occurrence of it in the command line
inverts the quiet-mode state. By default, XFER has quiet mode off. The first
occurrence of the
Q
option turns quiet mode on, the next turns it back off, and
so on. This is most useful if the option is specified in the
XFER_ARGS
environment variable (refer to
) to activate quiet mode by default but
in the current transfer session quiet mode will be deactivated.
R
Receive File(s):
This option specifies that files are to be received. With
Xmodem protocol, the option must be specified whenever receiving a file. The
option can be included in the
XFER_ARGS
environment variable (refer to
), forcing Xmodem protocol to default to receiving instead of sending
files.
With Zmodem, receive is the default if
no
file is specified on the command line
(for example,
XFER
/z
). The name of the file is sent by the transmitting side
before the file is transferred, and the file is received with that path and name.
To receive a file under Zmodem with a different name from the sender’s, use
the
R
option to force Zmodem into receive mode. Specify the new filename
after the
R
option on the receiver’s command line (See the
filename
(s)
option on
for information on specifying file-names.) When
Zmodem has been specified, using the
R
option without a filename is the same
as not using the option at all—the sender’s filename (and path) is used.
