About RFC2217 Function in eathernet to series(e2s) demo code

How to use following function? Such as the port parameter detail definition. And how to write the series code to call this function?

TelnetNotifyModemState(uint32_t ui32Port, uint8_t ui8ModemState)

其实我是想知道传进来的参数ui8ModemState每一个bit是怎么定义的?  我在RFC2217协议描述里,找到一个modemstateMask, 看样子读到相应bit 再一个个填进相应位置,就可以吧!先试试!
