BETWEEN COMPUTER AND COMPUTER THROUGH MODEL
24SII
When Computer A transmits data to Computer B through the Model
24SII DES, the data is received from Computer A and stored in a
512-character buffer which in turn retransmits it to Computer B. When
the buffer fills, the Model 24SII DES will make the DTR line low to
Computer A, signaling Computer A that it cannot accept more data.
When the Model 24SII DES retransmits the data to Computer B, the
Model 24SII DES will expect to see a high on the CTS line. When
Computer B cannot receive any more data, the Model 24SII DES will
expect to see a low on the CTS line.
When the buffer of the Model 24SII DES can receive more data, the
Model 24SII DES will make the DTR line high to Computer A.

NOTE: The Model 24SII DES permits XON/XOFF to be enabled or
disabled by port independently in the receive and transmit directions.
The description of handshaking functions below considers XON/XOFF
to be enabled in both directions. If XON/XOFF is disabled in one
direction, that direction will support hardware handshaking as
described in
Section 7.3.1
