Hi Guys, Getting problem while trying to configure the 2 Huawei/Tata Photon on DM365 ARM board. The two modems are detected by linux kernel having ports as ttyUSB0-2 and ttyUSB3-5. Individual single modem Configuration/setting works successfully. Gets the interface ppp0 up with IP address. Facing problem while trying to bring up both the modems. The first modem gets configured successfully. The problem comes while trying to get the second modem up. The second pppd command gives the "LCP: timeout sending Config-Requests" error and the modem hangs up. At a time only one modem is configured successfully. This works with either of the modem but not with both modems at same time Here the commands to configure both the modems. This command configure the modem /dev/ttyUSB0 successfully. ppp0 interface is created, IP address is assigned to it. # pppd connect 'chat -v "" AT OK ATDT#777~' /dev/ttyUSB0 9600 crtscts debug defaultroute ##Configuring the second modem ttyUSB3, gives LCP timeout error #pppd connect 'chat -v "" ATDT#777~' /dev/ttyUSB3 9600 crtscts debug nodefaultroute Thanks, Vandana The pppd command for second modem configuration gives the "LCP: timeout sending Config-Requests" error.
