preserved with this command. This sequence is ignored except when the printer is busy
due to an error condition.
Example:
MSComm1.Output = Chr$(&H1D) & Chr$(&H03) & Chr$(n)
Exceptions:
The command is ignored if n is out of range
An application using the DLE sequence must send ENQ within 100 milliseconds of DLE or
the printer will misinterpret the DLE and execute a Clear Printer command. Avoid this
possibility by using the 1D 03 n sequence that is handled exactly the same as 10 05 n.

According to “Ethernet RTC Protocol” setting ( 1F 11 ) , the using protocol and port
number are different. When “Ethernet RTC Protocol” setting is TCP, this command
effective in TCP 9100 port. “Ethernet RTC Protocol” setting is UDP, this command
effective in UDP 3000 port.
When send above command to the printer by Ethernet (UDP 3000 port), need to add
Sequence Number of 4 bytes before command.
In case of above command, send xxh xxh xxh xxh 1Dh 05h. “xxh xxh xxh xxh“ is Sequence
Number. The printer responses with same Sequence Number.
