Escape; Flow; Frack - Advanced Electronic Applications PK-88 Operating Manual

PK-88 OPERATING MANUAL
ESCAPE ON|OFF
Parameters: ON
OFF
The ESCAPE command selects the character to be output when an <ESCAPE> character is to be
sent to the terminal. The <ESCAPE> translation is disabled in Transparent Mode.
The ESCAPE character selection is provided because some computers and terminal emulators inter-
pret the <ESCAPE> character as a special command prefix. Such terminals may alter their displays
depending on the characters following the <ESCAPE>.
Set ESCAPE ON if your terminal requires it to avoid unexpected text strings from other packet
operators.
See the MFILTER command for information on character stripping (rather than character trans-
lation) in monitored packets.
FLOW ON|OFF
Parameters: ON
OFF
When FLOW is ON, type-in flow control is active. Any character typed on your keyboard causes
output from the PK-88 to the terminal to stop until any of the following conditions exist:
A packet is forced (in Converse Mode)
A line is completed (in Command Mode)
The packet length (See PACLEN) is exceeded
The terminal output buffer fills up
Canceling the current command or packet or typing the redisplay-line character also causes output
to resume. Type-in flow control is not used in Transparent Mode.
Setting FLOW ON prevents inbound or received data from interfering with your keyboard data en-
try. If you (and the person you are talking to) normally wait for a packet from the other end before
starting to respond, you can set
Some electronic mail and packet bulletin board systems may work best with FLOW set to OFF.
Some interface boards or computers with 'software UARTs' may be unable to send and receive
data at the same time. If you are using that type of computer, set FLOW to ON.

FRACK

n
Parameters:
FRACK is the FRame ACKnowledgment time in seconds that your PK-88 will wait for acknowledg-
ment of the last-sent protocol frame before resending or 'retrying' that frame.
After sending a packet requiring acknowledgment, the PK-88 waits for FRACK seconds timeout be-
fore incrementing the retry counter and sending the frame again. If the packet address includes
digipeat instructions, the time between retries is adjusted to:
Mnemonic: ES
The <ESCAPE> character ($1B) is output as '$' ($24).
The <ESCAPE> character is output as <ESCAPE> ($1B).
Mnemonic: F
Type-in flow control IS active.
Type-in flow control is NOT active.

FLOW

OFF.
Mnemonic: FR
1 to 15, specifying frame acknowledgment time-out in one second intervals.
