Hi,All: In my application I'm using a ARM7 (from NXP) with a serial Interface (RS232) to connect with a CDMA modem. After dial the number and received "CONNECT",beginning to exchange LCP data,but In the data of the ARM7 losesd the "FF 03",what's the reason?
Now it entries IPCP REQ: ARM: 7E FF 03 80 21 10 01 01 00 1A 03 06 00 00 00 00 //local IP 90 8B 7E but do not receive IPCP ACK.
