About the DOWNLOAD Program
The DOWNLOAD.EXE executable file is included on the distribution diskette when
you receive your operating software upgrade. While simply typing DOWNLOAD to
execute the program is adequate for most applications, the DOWNLOAD program
accepts several variables that modify its operation for special cases.
The full format for the download command is as follows;
DOWNLOAD
filename.ext /Pn /In /Bnnnn /Annn
The parts of the command are described below.
DOWNLOAD:
The root command. Starts the software download process. If no
parameters are specified the default values are used (see below) which is equivalent
to typing DOWNLOAD /PI /I4 /B38.4 /A3F8.
filename.ext:
Selects the software file to be downloaded. Operating software files
end with the extension .OUT. If no file is specified, the program downloads the first
file in the working directory that has the .OUT extension. Distribution diskettes
include only one software file, so it is rare that you would need to use the file name
in the download command.
/Pn:
Specifies the COM port to be used on the PC, where n is 1 through 4. For
example /P3 selects COM3. If no port is specified, COMl is used.
/In:
Specifies the system interrupt request line (IRQ) for the COM port, where n is
1-7. For example /I4 selects IRQ 4. If no IRQ is specified, IRQ 4 is used for COMl
and COM3 and IRQ 3 is used for COM2 and COM4.
/Bnnnn:
Specifies the baud rate for the COM port, where nnnn is 1200,4800,9600,
19.2, or 38.4. For example/B 19.2 sets the baud rate to 19.2 Kbaud. If no baud rate is
specified, 38.4 Kbaud is used.
/Annn: Specifies the COM port's base address in hexadecimal notation, where each
digit of nnn can be 0 through F. For example /A3F8 sets the base address for 3F8h. If
no base address is specified the base addresses 3F8, 2F8, 3E8, and 2E8 are used for
COMl through COM4, respectively.
