PPP Serial-Connection to Windows PC?

does anyone knows how to configure/program the ME (i have the developesystem with NET+OS 6.0) to connect via serialport to a windows pc. I tried the examples under …/ppp/iproute, but i doesn’t runs. I figured out, that the windows pc sends to initiate the connection first “CLIENT”, “CLIENT”, etc. After the partner(here the ME) would send an character, then the windows pc sends the frames for PPP. Does anyone has an example that works like this:
1.) Start Serialport COM1 on ME
2.) Wait for receiveing Character “CLIENT”
3.) Send CR
4.) End Serialport
5.) Start PPP on COM1
