I will do what you suggested. If the upgrade is successful I will upload it here. As to the work of PPP in the vanilla lwip 1.4.1, when trying to connect, quite often I used to receive the following debug log: ++++++++++++++++++++++ [DEBUG] Initializing PPP lcp_init: xmit_accm=0 0 0 0 upap_init: 0 pppOverSerialOpen: unit 0: Connecting pppStart: unit 0 ppp_set_xaccm[0]: outACCM=0 0 0 0 ppp_send_config[0]: outACCM=FF FF FF FF ppp_recv_config[0]: inACCM=0 0 0 0 lcp_lowerup: asyncmap=0 0 0 0 LCP: lowerup state 0 (LS_INITIAL) -> 2 (LS_CLOSED) auth_reset: 0 lcp_addci: L opt=2 0 lcp_addci: L opt=5 2FF6F209 lcp_addci: opt=7 lcp_addci: opt=8 pppWrite[0]: len=46 fsm_sdata(LCP): Sent code 1,1,20.

LCP: sending Configure-Request, id 1 LCP: timeout resending Config-Request state=6 (LS_REQSENT) ++++++++++++++++++++++++++++++ (This is just a snipet from the log.) Apparently, it meant that I did not receive anything from GPRS modem through the serial port. That happened quite often, however, successful connection did happen also. But when I started using GPRS VPN service from my cellular network provider this problem has not shown up yet. I have tested it several times and there was always a successfull connection. So I believe now, the problem was related to the quality of service and not to the PPP (1.4.1) implementation. Oleg -- You are receiving this mail because: You are the assignee for the bug.
