DLE EOT n

Hexadecimal 10 04 n
Decimal 16 4 n
[Range] 1

[Outline] This command sends the n-specified status at real time.
[Caution] • For the status sent, see the tables on the following pages.
• This command runs processing upon its reception.
• When sending the status, only one byte is sent without confirming the DSR signal status.
• The command is executed in the off-line state, reception buffer full state, and error state as
well.
• The user should note that the operation of this command is also executed when a data
sequence of <10>H<04>H<n> (1
Ϲ n Ϲ 3, n = 5) is received, other than this command.
<Example>
d1 = <10>H, d2 = <04>H, d3 = <1> in ESC * m nL nH [d]nL + 256
×
nH
• This command must not be used by interrupting the code sequence of other command
consisting of 2 bytes or more.
<Example>
If DLE EOT 3 is sent after sending up to ESC 3, attempting to send ESC 3 n from the host, it
will be processed as ESC 3 n = <10>H. Therefore, the use should take heed of this.
• If ASB has been enabled by GS a, it is necessary to distinguish the status by this command
from that of ASB. See “6. Interface” for how to distinguish them
• If n is beyond the range, this command will be ignored.
