Hi,
I am able to send SMS using AT commands and C outside chroot using
code spinet below
-------------------------------------------------------------------
#include <stdio.h>
#include <time.h>
#include <unistd.h>
#define MODEM_PATH "cu -l /dev/cuaU0 -s 115200"
int main()
{
FILE *out;
char s[40];
printf("Content-type: text/html\n\n");
snprintf(s, sizeof(s), "%s", MODEM_PATH);
~
~
~
~
~
~
return(0);
}
--------------------------------------------------------------------
however, running the program from within chroot, I get the message
/dev/cuaU0 - No such file or directory
All files needed by cu are properly copied to chroot and cu works fine.
Question:
1: How do i get /dev/cuaU0 device accessible under chroot?
2: Is there a better i.e more secure approach to access modem from
within chroot?
