• PBKillfw ON|OFF

{ON}

When ON, private and traffic messages will be killed (deleted) from your PBBS automatically after

they have been forwarded to another BBS. When OFF, these messages will not be killed, but will

be marked with the forwarded flag (F) to prevent them from forwarding again.

• PBLo [OLD|NEW][FIXED|VARIABLE]

{NEW VARIABLE}

When set to NEW, the PBBS will list messages to a user with the newest message (highest num-

ber) listed first When set to OLD, the oldest message will be listed first When the second parame-

ter is set to VARIABLE, the user may change the order of the listing by using the LO command in

the PBBS. When set to FIXED, the user cannot change the listing order.

• PBPerson ON|OFF

{OFF}

When OFF, the personal mailbox will allow messages to be sent to any callsign. These messages

may be forwarded to another BBS by the PBFORWRD command or as the result of being polled by

another BBS if the HTEXT is set in your KPC-9612. When this occurs, the PBBS will add an R: line

to the message indicating that it has been relayed by your station. When ON, only messages ad-

dressed to your MYCALL or MYPBBS callsign will be accepted in the mailbox. Messages entered

from the attached terminal may be addressed to any callsign. With PBPERSON ON, forwarding and

reverse forwarding will not include an R: line in the message, but only messages from your MY-

CALL will be sent, and only messages to your MYCALL or MYPBBS call will be accepted.

• PBRevers ON|OFF

{OFF}

When ON, the KPC-9612 will request a reverse forward after it has initiated a forward to another

BBS and sent its messages. When OFF, no reverse forward will be requested after initiating a for-

ward.

• PERsist

(= 0 – 255)

{63/63}

This command sets the value used to determine the probability of transmitting a packet after

SLOTTIME expires. This method of determining access to the radio channel has proven more Effi-

cient in sharing the frequency than using the DWAIT method. The higher the PERSIST value, the

more likely it is that your station will transmit when the channel is clear. A reasonable rule-of-

thumb for selecting the PERSIST value is to divide 256 by the number of users on the channel at

the same time. Using this method allows many users to share the channel and still be successful in

passing their data.
