VDM*.tmp

hello all,
i'm now developing a program to read text file and send all the value from text file via serial communication. After i sent all the value from text file, i remove that file because another text file will be generated. What i'm asking, why after i remove the .txt file, the file changed into VDM*.tmp and after several times my program stop working, how to prevent it ?. Here is my code :
#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
#include <dos.h>

#define PORT1 0x3F8

/*
Serial Port Address
COM1 0x3F8
COM2 0x2F8
COM3 0x3E8
cOM4 0x2E8
*/

void get_serial_data()
{
	int c;
	int counter;
	char buffer[100];	

	while(1)
	{
		c = inportb(PORT1 + 5);
		if(c & 1)
		{
			buffer[counter] = inport(PORT1);
			printf("%c", buffer[counter]);
		}
		if(kbhit())
		{
			break;
		}
	}		
}

void open_com_port()
{
	outportb(PORT1 + 1 , 0);   /* Turn off interrupts - Port1 */

	/*         PORT 1 - Communication Settings         */

	outportb(PORT1 + 3 , 0x80);  /* SET DLAB ON */
	outportb(PORT1 + 0 , 0x01);  /* Set Baud rate - Divisor Latch Low Byte */
				     /* Default 0x03 =  38,400 BPS */
				     /*         0x01 = 115,200 BPS */
				     /*         0x02 =  57,600 BPS */
				     /*         0x06 =  19,200 BPS */
				     /*         0x0C =   9,600 BPS */
				     /*         0x18 =   4,800 BPS */
				     /*         0x30 =   2,400 BPS */
	outportb(PORT1 + 1 , 0x00);  /* Set Baud rate - Divisor Latch High Byte */
	outportb(PORT1 + 3 , 0x03);  /* 8 Bits, No Parity, 1 Stop Bit */

Hello!

Isn't problem that you used slash symbol instead backslash in the path?

remove("D:/adtj/www/htdocs/skripsi/kdt.txt");

Do you use Borland c on Dos? It is possible that your proble can releated that compiler and linker...

If it is disturb you, you can use other compiler e.g. open watcom c for dos.
