Communication protocol
User commands consist of an ASCII-coded command string and - if
needed - a parameter separated by a space. The command parser
works non case sensitive.
The character received won't be echoed by the centrifuge processor
normally. You can tell the centrifuge to echo each character by
sending the
“echoon”
command. The user command and the return
string of the centrifuge will always be terminated with the characters
‘0x0A’ and ‘0x0D’ (CR and LF).
The command
“cmderror”
can be used to ensure the correct
execution of the last command.
