MX2A137REFGD Revision A MX2 Reference Guide
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.
Running XFER in quiet mode on the MX2 can have serious
consequences for serial-transfer performance, especially at high speeds.
At 115200 baud, transfers are four times faster if quiet mode is enabled
on the MX2 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 to activate quiet
mode by default but you wish to deactivate quiet mode for the current
transfer session.
R
Receive File(s)
This option specifies that files are to be received. With Xmodem
protocol, the option must be specified whenever you wish to receive a
file. The option can be included in the XFER_ARGS environment
variable, 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. If you wish to receive a file under Zmodem
with a different name from the sender’s original filename, you can use
the R option to force Zmodem into receive mode and then specify a
filename. (See the “filename(s)” option for information on specifying
filenames.) 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.
Note: The last transfer option, R or T, on the command line controls
whether to transmit or receive for the session.
