PQ-8P, PQ-8S

COMMAND 77: SERIAL-IN WORD LENGTH

Selects the Word Length of data received at the serial-in port. A new setting will not be effective immed- iately. To activate the new setting, cycle power on the interface.

VALUE

DESCRIPTION

7

7 Bits

*8

8 Bits

Example: &%Z77,7 sets the word length to 7 bits

COMMAND 78: SERIAL-IN STOP BITS

Selects the number of Stop Bits of a data stream received at the serial-in port. A new setting will not be effective immediately. To activate the new setting, cycle power on the interface.

VALUE

DESCRIPTION

*1

1

Bit

2

2

Bits

Example: &%Z78,2 sets the number of Stop Bits to 2

COMMAND 79: SERIAL-IN PARITY

Selects the Parity of a data stream received at the serial-in port. A new setting will not be effective immed- iately. To activate the new setting, cycle power on the PQ-8.

VALUE

DESCRIPTION

*0

None

1Odd

2Even

Example: &%Z79,2 sets the parity to even.

COMMAND 84: 6 LPI STRING

Used with Generic output protocol to define the 6 LPI string. This string represents the printer-specific command to set the printer to 6 LPI. Consult the printer’s user’s guide for the appropriate ASCII hex value representing the 6 LPI command. Whenever the interface receives a

6 LPI command from the host, it sends the string specified through Host/PC download command 84. If no string is specified, it will send the standard 6 LPI command for the active output protocol.

VALUE

DESCRIPTION

1(up to 25

Defines the 6 LPI

hex bytes)

string

1()

Deletes the 6 LPI

 

string

Example: &%Z84,1(1B 32) assigns the 6 LPI command for an Epson LQ-2500 printer (hex value 1B 32) in the PQ-8’s memory.
