The data required for the command is carried here. Each character can have a value of 0X00
to 0X7F i.e. 7 bits.
Checksum:
This is the sum module of the characters in the frame between the destination address and
the last data character inclusively. It is calculated thus:
DO
{
checksum = (cha checksum) AND 0x7F
}
FOR ALL CHARACTERS IN FRAME
End Flag:
A character 0XFE ends the frame.

Replies
Replies, when requested (e.g. 82), will consist of frames that contain the original command
value plus 0X40. So a request for an ident, 0x82, will elicit a reply of a frame containing 0xC2
and the ident string. (AM - 04Vn.n)
