From: Martin Xu <martin.xu(a)intel.com&gt; Using my Huawei EM770W modem, if set ACCM as 0x00000000, RXJ- event breaks PPP link, after IP package transmit for a while. Using default ACCM, the issue can be fixed. I tested it at China Unicom networks. --- gatchat/ppp_lcp.c | 8 +++++--- 1 files changed, 5 insertions(+), 3 deletions(-) diff --git a/gatchat/ppp_lcp.c b/gatchat/ppp_lcp.c index cc3e231..91a8b67 100644 --- a/gatchat/ppp_lcp.c +++ b/gatchat/ppp_lcp.c @@ -105,8 +105,7 @@ static void lcp_generate_config_options(struct lcp_data *lcp) static void lcp_reset_config_options(struct lcp_data *lcp) { - lcp->req_options = REQ_OPTION_ACCM; - lcp->accm = 0; + /* Using the default ACCM */ lcp_generate_config_options(lcp); } @@ -147,6 +146,7 @@ static void lcp_rca(struct pppcp_data *pppcp, const struct pppcp_packet *packet) ppp_option_iter_init(&iter, packet); while (ppp_option_iter_next(&iter) == TRUE) { + const guint8 *data = ppp_option_iter_get_data(&iter); switch (ppp_option_iter_get_type(&iter)) { case ACCM: /* @@ -155,7 +155,9 @@ static void lcp_rca(struct pppcp_data *pppcp, const struct pppcp_packet *packet) * which control characters MUST remain mapped when * the peer sends them. */ - ppp_set_recv_accm(pppcp_get_ppp(pppcp), 0); + + ppp_set_recv_accm(pppcp_get_ppp(pppcp), + get_host_long(data)); break; default: break; -- 1.6.1.3
