16.3 Zmodem Downloads

Using the Zmodem protocol to send files to and from the TS-5700 is simple and straightforward. The only
requirement is a terminal emulation program that supports Zmodem, and virtually all do. If you are using
Windows 95 or later for your development work, the HyperTerminal accessory works well.
To download a file to the TS-5700 from your host PC, execute DL.BAT at the DOS command line on the TS-
5700 (while using console-redirection from within your terminal emulator) and begin the transfer with your
terminal emulator. In HyperTerminal, this is 'Send File...' from the 'Transfer' menu.
To upload a file from the TS-5700 to your host PC, execute UL.BAT <FILENAME> at the DOS command line
on the TS-5700 and start the transfer in your terminal emulator. Many emulators, HyperTerminal among them,
will automatically begin the transfer themselves.
Occasionally there may be errors in transmission due to background solid-state disk operations. This is not a
problem -- Zmodem uses very accurate CRC checks to detect errors and simply resends bad data. Once the file
transfer is complete the file is completely error free.
For best results when using HyperTerminal, the hardware handshaking must be enabled in HyperTerminal. To
increase the download speed you could also use a ram disk on the TS-5700 to receive the download file, and
then copy to the Flash drive.
To declare a ram disk insert this line into the config.sys file: device=\dos\vdisk.sys /kbtouse=1024
Please note that the utility used to perform Zmodem file transfers on the TS-5700 side is called DSZ, produced
by Omen Technologies. DSZ is shareware -- it is not free. If you decide to use it, you are legally obligated to
pay Omen Technologies. Currently the cost is $20. Further info is available in the DSZ zip file located on the
utility disk, or contact Omen Technologies.
