receive data frame. Each port of the HP E2261A has a 2kByte FIFO and a 16kByte
SRAM receive buffer. When the HP E2261A receives data from the external device,
it passes the data from the UART to the SRAM receive buffer. When the FIFO is
empty, and the amount of data in the receive buffer is equal to or greater than the
< block_size >, the HP E2261A transfers the <
buffer to the FIFO. In general, the larger the <

Power-on/reset blocksize is 2048 bytes for all ports.

disables receive pacing (XON/XOFF) protocol.
Parameter Type
discrete
•
While the protocol is XON, the serial interface will send XOFF when the
buffer reaches the ...STOP threshold, and XON when the buffer reaches the
...STARt threshold.
•
The XON character is control Q (ASCII 17), The XOFF character is control S
(ASCII 19).
