Re: [Freeipmi-devel] IPMI Serial Interface (Terminal Mode) PowerPC

[Anand Babu Periasamy]

IPMI Terminal-Mode is different interface from serial driver. 

PPP, Terminal mode and native mode are different ways to access the
BMC through the serial port. You cannot access the serial interface
through inband.

With PPP, IPMI uses UDP protocol for communication. So the LAN driver
should work. 

With native serial interface, I haven't seen any users for it.

With Terminal Mode, upon a specific key stroke [say Esc(], BMC takes
control over the serial port and throws a console interface to IPMI.
The user interface for Terminal Mode is not a specification. I have
seen both command line and curses like interface. 

You can use any serial driver library and write a parser. It will be
highly vendor / firmware version specific though.
