Set Turn-Around Delay Command
ESC
t delay terminator
delay: 0 = none, 1 = 50 milliseconds, 2 = 100 milliseconds, 3 = 250 milliseconds
Response: none
Description: Allows the host controller to change the delay between the time the OIT
receives a command requesting data and the OIT’s response.
Example: PRINT CHR(27); “t0”; CHR(2)
Set Tab Character Width Command
ESC
z width terminator
width: 0 = no change, 1 = 1 character, 2 = 4 character, 3 = 8 character
Response: none
Description: Allows the host controller to set the width of each “tab stop” used by the HT
control code.
Example: PRINT CHR(27); “z2”; CHR(2)
Set Communications Parameters Command
ESC
B baud parity databits terminator
baud: 0 = no change, 1 = 300 baud, 2 = 600 baud, 3 = 1200 baud,
4 = 2400 baud, 5 = 4800 baud, 6 = 9600 baud, 7 = 19200 baud
parity: 0 = no change, 1 = space, 2 = mark, 3 = even, 4 = odd, 5 = none
data bits: 0 = no change, 1 = 7 data bits (1 stop bit if parity, 2 if no parity),
2 = 8 data bits & 1 stop bit
Response: none
Description: Allows the host controller to change the OIT’s baud rate, parity, and data bits.
Example: PRINT CHR(27); “B652”; CHR(2)
Enable Handshaking Command
ESC
H handshaking terminator
handshaking: 0 = all handshaking disabled
1 = software handshaking (XON/XOFF) enabled (Interactive mode)
2 = hardware handshaking (RTS/CTS) enabled (Interactive and Block
modes)
3 = software and hardware handshaking enabled (Interactive mode)
Response: none
Description: Allows the host controller to enable or disable serial handshaking.
Example: PRINT CHR(27); “H0”; CHR(2)
Set Operating Mode Command
ESC
M mode address terminator
mode: 0 = no change, 1 = interactive, 2 = block, 3 = network
address: 01 to FF (ASCII hexadecimal)
Response: none
Description: Allows the host controller to change the OIT’s operating mode and
network address.
Example: PRINT CHR(27); “1”; CHR(2)
