In the converse mode, characters entered from the terminal will be sent as a packet, or sequence
of packets, to the receiving station. These commands are used by the TNC to make those packets.
When one of the following conditions is satisfied, the input characters will be considered as an
information frame (I frame) and sent.
l The specific characters are input : SENDPAC
l Relative command: CR
l When they reach pre-determined length: PACLEN
l When the pre-set time is elapsed: PACTIME and relative CPACTIME
You may transmit different frames as one packet. The maximum number of these frames can be
determined with MAXFRAME command.
4-6-1 SENDPAC command
abbrev.: SE default: $0D parameter: 0-$7F
example: SENDPAC $0D
In the converse mode, when the letter code specified with this parameter is entered, the letters
followed by the code is considered a complete packet (information frame=I frame) and will be sent
out. Default is CR. The codes set at this parameter won’t be included in the frame.
