SY – Send Y-Modem
Allows a file to be sent from the DAB to the users computer via the serial port.
Most any popular terminal program written in the past 10-15 years will support Y-Modem file transfers. Since each
program is different, please consult that software’s documentation for use of the file transfer capabilities of your terminal
emulation program.
The filename you wish to download into your computer should be specified on the command line, and needs to exist in the
present working directory.
Example:
7kDAB-\>sy config.ini
Start your YMODEM Download now.
At which point you would start your file transfer software.
RY – Receive Y-Modem
Allows one or more files to be sent to the DAB from the users computer via the serial port.
Example:
7kDAB-WAV\4300>ryCCCCC
The “C”’s shown in the example above are sent periodically by the DAB to signal to the host computer that the DAB
wishes to start receiving files using the CRC checksum method. One startup character is sent every 3 seconds, and up to
20 attempts are made before timing out.
LO – Logout
This command simply terminates a command line session, and will cause a modem to disconnect.
REBOOT – Reboot DAB
This command unceremoniously causes the DAB to reboot. It may be used to take advantage of new settings in the
CONFIG.INI file.
SMHOST – Force Smart Host Present Flag
This command is needed after a Reboot command is issued in order to simulate a special handshake sequence that
occurs when the 7K controller containing Version 2.04 software first powers up. Unless this handshake sequence is seen
by the DAB, some of the more advanced features, such as being able to send commands to the 7K, will be locked out.
Do not issue this command unless your 7K controller has Version 2.04 software.
