LCP terminated by peer, id=0x5

I use a GPRS modem, and attach ISP called "TDC" in Denmark, then ppp server send back LCP TermReq. But HSPA modem works. the log is as below:

Is this issue related about timing of ppp packet transmission? I use this ppp package in different OS kernel, Linux works, but RTOS fail.

[Amophis666]

After I check the RFC for LCP/CHAP/IPCP, the packet tx/rx log above is correct, now I focus on the timing of packet transmission in different OS kernel. next step, I would like have millisecond-level time stamp for these packet log.

Which modem are you using?
