eYe: no, I am not trying to do PPP/SLIP. I need a driver which will redirect COM port (data, handshake lines atc.) to TCP/IP.
On the other side there will be a box with 8 RS-232 ports and LAN port. This box will listen on the LAN for packets from the PC and will convert them back to RS-232 signals.
So, any application which is normally running on PC and using COM ports can run and use those "remote" COM ports.
There are commercial units which do exactly this. They have 1, 2, 4, 8 RS-232 ports.
I am building my own unit and I need a PC Windows driver for it.
