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
