LDC (Link Destination Card) can assert a signal, UXOFF#,
which causes it to transmit an XOFF code to the LSC (Link Source Card).
This stops data transmission from the LSC. When the signal is
de-asserted, an XON code is transmitted to the LSC which allows transmission
to resume.
UXOFF# is active afer 512 bytes are received and not read out at LDC.
