Timewave PK-900, Operating Manual, Page: 227 / 392

________________________________________________________________________________
Flow ON|OFF Default: ON
Mode: All Host: FL
_________________________________ Parameters: __________________________________
ON - Type-in flow control IS active.
OFF - Type-in flow control is NOT active.
________________________________________________________________________________
When FLOW is ON (default), any character typed on your keyboard causes output
from the PK-900 to the terminal to stop until any of the following occurs:
o A packet is sent on either Port (in Converse Mode)
o A line is completed (in Command Mode)
o The packet length on either Port (See PACLEN) is exceeded
o The current packet or command line is canceled
o The redisplay-line character is typed
o The logical packet channel or Radio Port is changed
Setting FLOW ON prevents received data from interfering with your keyboard data
entry. When FLOW is OFF, data is sent to the terminal whenever it is available.

FRack "n/n" Default: 5/5 (5 sec.)
Mode: Packet Host: FR
_________________________________ Parameters: __________________________________
"n" - 1 to 15, specifying FRame ACKnowledgment timeout in 1 sec. intervals.
________________________________________________________________________________
FRACK is the FRame Acknowledgment time in seconds that your PK-900 will wait for
acknowledgment of a sent protocol frame before "retrying" that frame. FRACK may
be different for each Radio Port, and in fact a setting of 8 is recommended for
HF packet operation.
After sending a packet requiring acknowledgment, the PK-900 waits for FRACK
seconds before incrementing the retry counter and sending another frame. If the
packet address includes any digipeaters, the time between retries is adjusted to:
Retry interval (in seconds) = "n" x (2 x m + 1)
(where m is the number of intermediate relay stations.)
When a packet is retried, a random wait time is added to any other wait times.
This avoids lockups where two packet stations repeatedly collide with each other.

FREe Immediate Command
Mode: All Host: FZ
________________________________________________________________________________
Typing "FREE" displays the number of usable bytes left in the MailDrop, as in
"FREE 16996." This may be useful to a Host mode application using the MailDrop.
The FAX mode is only available only if the FREE command shows at least 3742
bytes free. You must kill MailDrop messages until the number reaches this level
if you wish to operate FAX.
