Send_String Escape Sequences - AMX DXLink Multi-Format SMF-D Instruction Manual

SEND_STRING Escape Sequences

The DXLink Fiber units support several special SEND_STRING escape sequences. If any of the character combinations
listed below are found anywhere within a SEND_STRING program instruction, they will be treated as a command and
not the literal characters.
ESCSEQON
Use the
ESCSEQON
These commands are sent to Port 1.
SEND_STRING Escape Sequences
Command
27, 17
Send a break character for a specified
duration to a specific device.
27, 18, 0
Clear the ninth data bit by setting it to 0
on all character transmissions.
27, 18, 1
Set the ninth data bit to 1 for all
subsequent characters to be
transmitted.
27, 19
Insert a time delay before transmitting
the next character.
Note: For a listing of all supported Telnet commands, see page 95.

and NetLinx SEND_COMMANDS to control whether these are active or not. The
command must precede the Escape Sequences, otherwise the strings will be processed normally.

time = 1 to 255 (measured in 100 microsecond increments)
Sends a break character of 1 millisecond to the RS232_1 device.
Sets the RS232_1 device's ninth data bit to 0 on all character
transmissions.
Sets the RS232_1 device's ninth data bit to 1 on all character
transmissions.
time = 1 to 255. Measured in 1 millisecond increments.
Inserts a 10 millisecond delay before transmitting characters to the
RS232_1 device.
