440-1.EXE COM1 version
440-2.EXE COM2 version
440.doc this file
440-x.EXE is a stand alone compiled basic program designed to control
the KENWOOD 440s (NOT 940) from the keyboard of an IBM-PC computer through
serial ports COM1 or COM2. It is designed to run from a single command
line or through the menus provided in the program itself. By entering all
440-x commands from the command line the program can be used with the
new "!" DOS shell command in version 4.2 of W0RLI CPBBS.
EXAMPLE of a typical command used in the FWD.MB file:
!b <DOS shell command for port B of the CPBBS
440-2 20 5 <440-2.EXE command string (COM2:)
*** EOF <END of dos shell
GB0023F W0RLI <Beginning of next forward list
W0RLI
*** EOF
In the above example the "440-2" runs the 440-2.EXE program then
picks option "20" (SELECT MEMORY CHANNEL) and finally "5" which
selects channel 5. This same kind of command sequence could be used
in the autoexec file to initialize the radio on startup.
This program was written to allow a handicapped fellow ham control his
radio from the keyboard of his PC. My original intent was to write the
thing in C but I could not figure out how to control the PORTS and make
use of the COMBIOS etc.. I knew I could write the program in a few
hours in BASICA but I also knew the result would limit it's operation
to COM1 and COM2 only. To make a long story short I am making the program
available now in compiled basic form while I await additional information
on the control of the communication ports using the COMBIOS programs.
I DO NOT have an interface to control my 440s yet but it is on order so
if any of you have any comments or suggested additions to the program
please leave a message so I can add the features to it.
COMMENT:
One of the considerations for purchasing the 440 was its ability
to be controlled from the keyboard. Since it has a built in auto tuner,
I am many others assumed we could activate the tuner form the computer,
NOT TRUE for the 440. It seems to me that the ability to change frequencies
with the tuner is nearly useless. I have contacted Kenwood and they indicated
that I was the first to complain. If they were to receive "enough" complaints
they would consider a modification to offer tuning from the keyboard. In
my particular case I use the 440 on our Navy MARS packet net. This requires
several off the wall frequencies and tuning is a must on several of them.
For a handicapped operator this capability might mean the difference between
total enjoyment of the ham experience and added frustration. If you agree
that auto tuning is a much need 440 capability, please call or write Kenwood
in California and ask them to design a modifications for us. Thanks!
