Send with ASCII Conversion, with Response:
(Sequence No. 600 (Hex 0258))
• Send word order: Rightmost to leftmost
• Receive word order: Leftmost to rightmost
This sequence converts the specified data beginning with the command code to ASCII and sends it to the
specified Unit. The response is converted to hexadecimal and stored starting at the specified word.
Send Data Word Allocation (3rd Operand of PMCR(260))
First word of
send data
Note 1. Set the number of send bytes to twice the number of bytes in memory. This is necessary because the
data is converted to ASCII data before being sent.
2. Frames are created and sent starting from the rightmost to leftmost word of the address in I/O mem-
ory.
