Read Data (Response)
Read data is returned according to the data format and the order in which read
information was registered using QQ. If "Completion Flag" has been specified,
then bit data (ON or OFF) is returned. If "Word" has been specified, then word
data is returned. If "PV" has been specified for timers/counters, however, then
the PV is returned following the Completion Flag.
Data Break (Response)
The break code (, ) is returned between sections that are read.
Aborts the Host Link operation that is currently being processed, and then en-
ables reception of the next command. The ABORT command does not receive a
response.

host computer. The INITIALIZE command does not use node numbers or FCS,
and does not receive a response.
This command is supported by CPM2A/CPM2C PCs only.
This is the response format used when the PC's TXD(48) instruction is executed
in Host Link communications mode. There is no command associated with EX.
TXD(48) converts the specified data into ASCII and transmits it to the host com-
puter with this format. The response can contain up to 122 characters of ASCII
data. (TXD(48) does not support multiple frames.)
