Roland DXY-1300 Command Reference Manual page 134

P1:
This parameter sets the byte number of a data block sent from the com puter to the
DXY-1000 series. When receiving an ENQ character, the DXY-1000 series out­
puts an ACK character if the remaining buffer capacity is above the values set by
the P1. The parameter range of P1 is from 0 to 15358.
(Default value: 80)
P2:
This parameter sets an ENQ character. For this character, usually [ENQ]CHR$(5)
is used. But if you specify 0, the ENQ/ACK handshake is not set.
(Default value: 0)
P3 to P12:
These parameters set an ACK character only if you set P2. You can set up to 10
characters. For this character, usually [A C K ]C HR$(6) is used. If you specify 0, any
ACK character is not output, but only the output term inator set by the ESC.M com
mand is output.
(Default value: 0)
EXAMPLE: PRINT #1,CHR$(27);".H 128;5;6:" ;
In this case, the byte number of a data block becomes 128. The ENQ character is
[ENQ]CHR$(5) and the ACK character is [A C K ]C HR$(6).

• EXPLANATION
This command is used when you want the X o n /X o ff handshake and the ENQ/ACK hand
shake mode 2. If you om it all the parameters (in case you send [ESC].I:), handshakes are
not available. If the com puter sends an ENQ character to the DXY-1000 series, the DXY-
1000 series always outputs an ACK character. This is also called a " dum m y handshake" .
P1:
For the X o n /X o ff handshake, this parameter sets the limit of the remaining buffer
capacity. If the remaining buffer capacity is below the values set by the parameter
p1, the DXY-1000 series outputs an X off character.
For the ENQ/ACK handshake mode 2, the parameter P1 sets the size of a data
block. The parameter range is from 10 to 15358.
(Default value: 80)
EXAMPLE: P R I N T #1,C H R $ ( 27 ) ;" .I 1 0 0 ; ; 1 7 : " ; C H R $ ( 2 7 ) ; " . N ;
1 9 :" ;
If the remaining buffer capacity reaches 100 bytes, the DXY-1000 series outputs
an Xoff character [DC1].
