[ts-7000] Re: ts-gsm1 reset modem only 0x11e00143

["wawan_wiratno" <>]

Hi Don,
this function is resetting the whole board not the modem only

int gsmpwron() {
        printf("powering on...\n");
        if (pc104base==NULL) { 
                printf("device not found"); 
                return(-1); 
        }
        *gsmstat=(0x01); /* set power on */
        usleep(4000000); /* wait for power change to happen */
        printf("modem on\n");   
        return 0;
}

same as my command line using poke8
poke8 0x11e00143 0x01

what I need is resetting the modem only not entire board.

many thanks

Wawan
