Serial Interface Subsystem
The MMC firmware implements a communication protocol over the payload and/or serial debug
interfaces. The communication is in the form of formatted ASCII strings.
The Serial Interface Protocol Lite (SIPL) is based on the IPMI-defined Terminal Mode of the
serial/modem interface. The following sections describe the SIPL:
“Terminal Mode Messages and Commands,” on page 61
“Terminal Mode Line Editing,” on page 63
“Supported PPS Extension Commands,” on page 63
Terminal Mode Messages and Commands
Terminal Mode Message Format
Terminal Mode messages have the following format:
[<message data>]<newline>
The left bracket and the right bracket plus
<newline>
characters serve as START and STOP
delimiters for a message. The MMC does not support multi-line IPMI messages.
Raw IPMI Messages
The SIPL supports raw IPMI messages that are entered as sequences of case-insensitive hex-
ASCII pairs, each pair optionally separated from the previous one with a single
<space>
character. What follows are examples of raw IPMI request messages in Terminal Mode:
[18 00 22]<newline>
[180022]<newline>]
The MMC handles raw IPMI messages in the same way as it handles IPMI/PICMG/AMC
messages coming from the IPMB-L bus and, with the exception that IPMI/PICMG/AMC replies
are routed to the interfaces from which the respective requests have come (i.e. either the serial
debug or payload interface of the MMC).
Terminal Mode Text Commands
The SIPL does not support Terminal Mode ASCII text commands defined by the
IPMI
Specification (section 13.7.8)
