hi all
i am trying to exute this whole shell command
in our .cpp programme

/usr/sbin/pppd /dev/ttyS0 115200 crtscts debug dump defaultroute usepeerdns noauth connect '/usr/sbin/chat -v "" at+crm=1 OK "atdt#777" CONNECT' mru 254"

can any body tell how to execute this whole command in our .cpp file using system call.

i am trying like this :
char as[100]="/usr/sbin/pppd /dev/ttyS0 115200 crtscts debug dump defaultroute usepeerdns noauth connect '/usr/sbin/chat -v "" at+crm=1 OK "atdt#777" CONNECT' mru 254"

system(buffer);

try with the below:

char as[100]="/usr/sbin/pppd /dev/ttyS0 115200 crtscts debug dump defaultroute usepeerdns noauth connect \'/usr/sbin/chat -v \"\" at+crm=1 OK \"atdt#777\" CONNECT\' mru 254"

Here I have prepended scape charecter for each " and '. I have tried the similar type of command in my machine. It is working fine.
I will suggest one more thing. Why you are relying on system library call. You can try with popen call also.
