port. sio_open() ensures the serial port has the correct setup. Just in case I might have this wrong, is this their expected function? For staring up lwip and configuring for slip I essentially do the same procedure as when I was trying to use the loopback driver: ...
函数sio_read()在pppInputThread中重复调用。它会阻塞等待,直到超时或请求缓冲区被填充,会从串行设备上读取数据。如果调用了sio_read_abort()那么必须废弃掉sio_read()。在sio_read与sio_read_abort之间这样的软连接关系必须被开发者自己实现,可以通过全局变量实现,可以通过RTOS的事件实现等。超时时长需要较小,大小...
