+It puts the modem into multiplex mod (using AT+CMUX), and then dispatch the serial lines

+you can use `ptsname` to get the name of the slave.

+
+the program will open several pseudo devices, and wait for the user to write into the slave, or for the modem to write into /dev/ttySAC0.
+The data written bu user into the slave will be read from the pseudo device and the progam transfer them into dev/ttySAC0.
+The data written by the modem into dev/ttySAC0 will be written by the software into the pseudo term and read by the user on the slave.

+** How does we connect a sys/ object to an actual hardware operation. e.g GSM
+The reset pin of the GSM module is connected to GPB6 pin of S3C2 CPU. This connection is defined in the file :
+ **./include/asm-arm/arch-s3c2410/gta02.h**: #define GTA02_GPIO_MODEM_RST S3C2410_GPB5
+Then in the file **./arch/arm/plat-s3c24xx/neo1973_pm_gsm.c**, we have :
+ neo1973_gpb_setpin(GTA02_GPIO_MODEM_RST, on);
+
+** Ubootize
+see [[u-boot]]
+That will create a uImage
+
+** Flash
+We use dfu-util for that :
+ sudo ./dfu-util -a kernel -R -D uImage
