XON/XOFF
An XOFF character turns the base transmission off until the base receives an
XON character. There are two situations for XON/XOFF:
•
XOFF is received before the base has data to send. When the base has data
to send, it then waits for an XON character before transmission. The base
waits up to two seconds to receive the XON. If the XON is not received
within this time, the base issues an error indication and discards the data.
•
XOFF is received during a transmission. Data transmission then stops
after sending the current byte. When the base receives an XON character,
it sends the rest of the data message. The base waits indefinitely for the
XON.
