I check the data on the port, and find one issue. i use chat util to dial ATD*99***1#, and it got the CONNECT and other data (I guest it is the REQ from the peer) 0d 0a 43 4f 4e 4e 45 43-54 0d 0a (CONNECT) 7e ff 7d 23 c0 21 7d 21-7d 21 7d 20 7d 32 7d 22 7d 26 7d 20 7d 2a 7d 20-7d 20 7d 23 7d 24 c0 23 7d 27 7d 22 7d 28 7d 22-55 83 7e
However, the pppd seems to ignore the REQ, sent [LCP ConfReq id=0x1 <asyncmap 0x0>] rcvd [LCP ConfNak id=0x1 <asyncmap 0xa0000>] sent [LCP ConfReq id=0x2 <asyncmap 0xa0000>] rcvd [LCP ConfAck id=0x2 <asyncmap 0xa0000>] rcvd [LCP ConfReq id=0x1 <asyncmap 0xa0000> <auth pap> <pcomp> <accomp>] sent [LCP ConfRej id=0x1 <pcomp> <accomp>] rcvd [LCP ConfReq id=0x2 <asyncmap 0xa0000> <auth pap>] sent [LCP ConfAck id=0x2 <asyncmap 0xa0000> <auth pap>] PAP authentication succeeded sent [IPCP ConfReq id=0x2 <addr 0.0.0.0> <ms-dns1 0.0.0.0> <ms-dns3 0.0.0.0>] rcvd [IPCP ConfReq id=0x1] rcvd rcvd [LCP TermReq id=0x3] Will that REQ be the point?
