Reception Format When
TXD(––) is executed, the data stored in the words beginning with the first
send
word is converted to ASCII and
output to the host computer as a host link
command in the format shown below. The “@” symbol, node number, header
code,
FCS, and delimiter are
all added automatically when the transmission is
sent.
At the host computer
, it is necessary to prepare
in advance a program for
interpreting and processing this format.

One byte of data (2 digits hexadecimal) is
converted
to two characters in ASCII
for
transmission, the amount of data in the transmission is twice the amount of
words
specified for TXD(––). The maximum number of characters for transmis
-
sion is 122 and the maximum number of bytes that can be designated for
TXD(––) is one half of that, or 61.
