是否在PPP通道上交互过,是不是看数据口是否有PPP数据吗?
我看了一下,数据口有PPP数据,大概如下:
437942 ms : PPPVSP! Read From USB: Notice! Read will be timeout in -1 ms
437948 ms : PPPVSP! COM Notifier: Notice! New Item into the Read Queue, will notify the COM MDD!
437957 ms : PPPVSP! Read from Read Queue: Get All Data in Node!
437962 ms : PPPVSP! Read from Read Queue: Succeed! Read 19 Bytes
437968 ms : PPPVSP! Read from Read Queue: Error! No data in Read Queue!
PPPVSP! Get something from 6280 Interrupt Pipe in InterruptThread!
PPPVSP! Get line state from 6280 Interrupt Pipe in InterruptThread, before invoke ModemSignal!
PPPVSP! ParseNotification Completed, the value of dwModemStatus is 0xa0
PPPVSP! Read From Interrupt Pipe: Notice! Read will be timeout in -1 ms
438034 ms : PPPVSP! Notice: PPPVSP will write 5 Bytes in 1250 msec!
438040 ms : PPPVSP! Succeed: Write 5 Bytes into USB!
438045 ms : PPPVSP! COM Notifier: Notice! Write to USB complete, will notify the COM MDD!
读写数据都有。
