retransmission of all the frames in an IO. I need to find Dr Pat's old DIB

ESCON is synchronous, where after sending a buffer, it would wait for
acknowledgement before sending the next buffer.
FICON is async, where it sends buffer after buffer without waiting
Mike,
Then how did ESCON use data buffers for flow control?

1. PPRC-XD and PPRC are very different animals. PPRC-XD is capable to work on
any distance, while PPRC is limited by speed of light which is not planned to
change.
2. ESCON vs FICON did huge difference not only in speed (bit

Hello All,
Please could you point me to any doc explaining the differences between the 2.
Any important, obscure, techdocs or KB page or some such as well.. ?

PPRC-XD is *inconsistent* copy
for migration like FDR/PAS and TDMF.
