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)
Set Line Terminator Command
ESC
T lineterminator terminator
line terminator: 0 =
ETX
, 1 =
CR
, 2 =
LF
, 3 =
CR/LF
Response: none
Description: Allows the host controller to change the line terminator.
Example: PRINT CHR(27); “T1”; CHR(2)
General Purpose Control Commands
Echo Back Text Command
ESC
e text terminator
Response: text terminator
Description: Causes the OIT to echo back the ASCII characters sent (up to 40
characters). Each character is stored by the OIT until the terminator is received,
at which time the entire string is sent back to the host controller.
Example: PRINT CHR(27); “eHello!”; CHR(2)
