Thank you for the input. I found a way to print ASCII. It is a little more complex than your solution.

I added the following code to my “for” loop.


//Convert a string to a...

I am 71 years old and haven’t programmed in C for many years. So, this is going slow.
I am using Borland C++ IDE to write 16 bit code for a picoFlash single board computer with a 186 compatible...

Thank you all for the inputs. I added the L suffix and the warning went away.
I want C code. The IDE picked the .CPP suffix for the source file name.
I will pay attention to this in the future.

I am trying to get rid of the 117 warnings in the code I was given to modify. The warning I am working on now is shown by”


#include <stdio.h>
int main()
{
long fpos;

Thank you all for your comments. I solved my problem by changing the overhead in what I was doing. The download that took six minutes now takes six seconds.

I ran out of DGROUP memory so I had to create the following variable


volatile char far strfarResponseString[4096];


I created a far pointer in my function and used it as below

The hyper terminal feature is already used in this system. The VB6 program doesn't have access to it.

I don’t know how to find the “maximum theoretical bandwidth” but some related factors are:

Thank you Adak

I tried this and it works.

Any idea what the difference in heating might be between this approach and the tight “for” loop?

OK Jim

I created a small modification to your program. I had to add #includes. I added print before delay

#include <stdio.h>

Thank you for the reply Jim.

Yes I am still using the Borland C++ 4.52 IDE. I understand that delay should be in milliseconds. I added the comment about 500 seconds just in case it was in...

Thank you for the reply Tim.

Thank you both. This clears things up for me a bit.

I'm not sure how to interpret function syntax. I am using Borland
C++ IDE version 4.52 to create C code.

The Syntax for fopen is:

FILE *fopen(const char *filename, const char *mode);

How embarrassing. Thank you for the quick response.

In an attempt to debug this problem, I have added printf statements to see what is happening when the code is running.

The printf statement containing “#103D” gives a good value for “FirstPtr”...
