After entering the xmodem command the unit will wait for your terminal program to start
transmitting the file. When the upload is complete and the file has been saved, the unit will
respond with the OK result code.
A remote XMODEM upload can also be initiated by establishing a Telnet session over ISDN,
and then issuing the xmodem command from the remote terminal.
USB Support
Most TransPort router come equipped with USB ports that you can use to connect Mass
Storage Devices (MSDs) such as external hard drives or flash-memory pen drives. All the
files on the USB device will be listed under the USB Directory Listing heading on the
Administration - File Management > FLASH Directory page.
Note:
The USB storage device must be formatted using the FAT16 or FAT32 file system.
When the USB storage device is first inserted into the unit, the operating system looks for a
file named “autoexec.bat”, and if found, executes it. Other batch files can be executed by
pressing the reset button one or more times. The batch file to be executed must be called
“pb<n>.bat”, where <n> is the number of times the reset button is to be pressed in order
to execute the file.
SD Memory Card Support
Some TransPort routers are available with internal SD memory card, the drive letter
assigned to this card is “s:”. To access the SD memory using an FTP client, the subdirectory
assigned is “sdmmc”. The SD card can be used in the same way as USB MSDs. The SD card
is internal and not removable.
Batch Control Commands
Any batch file can contain one of the following two control lines: ERROR_EXIT or
ERROR_RUN. If ERROR_EXIT is specified in a batch file, any commands run after that point
in the file will cause the termination of the batch file if that command causes an error (for
example, attempting to delete a file that does not exist). ERROR_RUN can be used to return
the operation to default, which is to continue the execution of the batch file commands.
USB Filing System Commands
The USB storage device will respond to any of the standard filing system commands. For all
filing system commands, the USB storage device is regarded as drive u:.
Note:
The unit does not support sub-directories. Any sub-directories on the USB device will appear
with a size of 0 bytes on the Administration - File Management > FLASH Directory
page.
Example 1:
To display the contents of the USB storage device, you would enter the command:
dir u:
SERIALS.TXT 1843
EVENTL~1.TXT 1449
USB.TXT 4278
MASSR1~1.TXT 1255
