File descriptor interface driver
io-net -d fd fd=device[,option[,option ...]] ... &
|Use commas (,) to separate the options (not spaces).|
The devn-fd.so driver uses file-descriptor based I/O (i.e. open(), read(), write(), and so on) to receive and transmit packets. It provides the Network Manager (io-net) with reliable data transfer over any media supported by a file-descriptor-based server process.
|The devn-fd.so driver does not support multicast addresses.|
For example, you could use devn-fd.so to connect two machines with a null-modem RS-232 serial cable. By using file-descriptor I/O to the serial devices, devn-fd.so would implicitly use a serial driver and set up a logical network link.
Start io-net using the FD driver and the full TCP/IP stack:
io-net -d fd fd=/dev/ser1,mac=0023456789AB,ahdlc -p tcpip ifconfig en0 10.0.184
You must specify the fd option when using this driver.
