PK-88 OPERATING MANUAL
PACTIME EVERY|AFTER 'n'
Parameters:
'n'
-
0 to 250 specifies 100-millisecond intervals.
EVERY
-
Packet timeout occurs every 'n' times 100 milliseconds.
AFTER
-
Packet timeout occurs when 'n' time 100 milliseconds
elapse without input from the computer or terminal.
A PACTIME parameter is always used in Transparent Mode. PACTIME is also used in
Converse Mode if CPACTIME is ON.
When EVERY is specified, the characters you type or send from disk are packaged
and queued for transmission every 'n' times 100 milliseconds.
When AFTER is specified, the characters you type or send from disk are packaged
when input from the terminal stops for 'n' times 100 milliseconds.
A zero-length packet will never be produced. The timer is not started until the first
character or byte is entered.
A value of 0 (zero) for 'n' is allowed; zero means packets are sent with no wait time.
PARITY 'n'
Parameters:
'n' -
0 to 3 selects a parity option from the table below.
PARITY sets the PK-88's data parity for terminal or computer data transfer according
to the following table:
The parity bit, if present, is stripped automatically on input, and is not checked in
Command and Converse Modes.
In Transparent Mode all eight bits (including parity) are transmitted in packets. When
'no parity' is set and AWLEN is 7, the eighth bit is set to 0 (zero).
Mnemonic: PACT
Mnemonic: PAR
0 = no parity
1 = odd parity
2 = no parity
3 = even parity
5-74
Default: AFTER 10
Default: 3 (even)
