NOTES:
LEGEND:
A change in the status of the CTS line was detected on the HDLC channel. The SCC sta-
tus register may be read to determine the current status.
A change in the status of the CD line was detected on the HDLC channel. The SCC status
register may be read to determine the current status.

NOTE: TXB event shown assumes all three bytes were put into a single buffer.
1. RXB event assumes receive buffers are 6 bytes each.
2. The second IDL event occurs after 15 ones are received in a row.
