OMI messages are defined in terms of these 6 fields:

• Short integer <SI>: 1 byte represents an unsigned integer ranging from 0 to 255.

• Very long integer <VI>: 4 bytes represent an unsigned integer ranging from 0 to 2³²–1. The bytes are sent in order of increasing significance, from low to high.
• Short string <SS>: a counted string comprising a 1 byte length <SI> followed by 0 to 255 bytes of data.
• Long string <LS>: a counted string comprising a 2 byte length <LI> followed by 0 to 65 535 bytes of data.
