PQ-8P, PQ-8S

COMMAND 50: SHARING PORT TIMEOUT

Selects the sharing port timeout value. This is the time interval before the interface automatically switches from the parallel or serial sharing port to check for data from the host.

VALUE

DESCRIPTION

4 to 60

4 to 60 seconds

*8

Default

Example: &%Z50,10 sets the time interval to 10 seconds.

COMMAND 56: PARALLEL PORT INITIALIZATION STRING

Allows the user to define a parallel- port initialization string of up to 25 ASCII bytes, which is stored in the memory of the interface card. The string is sent to initialize the printer for parallel-port printing after host printing has occurred. To aid in readability, a single space is allowed between hex bytes. Refer to Section

5.3for more information.

VALUE

DESCRIPTION

1(up to 25

Defines the init

hex bytes)

string

1()

Deletes init string

Example: &%Z56,1() deletes the hex strings previously defined as the parallel-port initialization string.

*Factory-default setting

COMMAND 58: SERIAL PORT INITIALIZATION STRING

Allows the user to define a serial-port initialization string of up to 25 ASCII bytes, which is stored in the memory of the PQ-8 card. The string is sent to initialize the printer for serial-port printing after host printing has occurred. To aid in readability, a single space is allowed between hex bytes. Refer to Section 5.3 for more information.

VALUE

DESCRIPTION

1(up to 25

Defines the init

hex bytes)

string

1()

Deletes init string

Example: &%Z58,1() deletes the hex strings previously defined as the serial port initialization string.

COMMAND 76: SERIAL-IN BAUD RATE

Selects the Baud Rate for data received at the serial-in port. A new setting will not be effective immediately. To activate the new setting, cycle power on the PQ-8.

VALUE DESCRIPTION

038,400 baud

119,200 baud

*2

9,600 baud

34,800 baud

42,400 baud

51,200 baud

6600 baud

7300 baud

Example: &%Z76,0 sets the receiving baud rate to 38,400
