Epson MFJ-1278B manual Cpactime ON/OFF, Cr On/Off

MFJ-1278B MULTI-MODE OPERATIONAL COMMANDS

CPACTIME ON/OFF Mode: Packet Default: OFF

Parameters:

ON Packet timeout is used in Converse Mode.

OFF Packet timeout is not used in Converse Mode.

This command enables the periodic automatic sending of packets in Converse Mode. This feature may be used for computer communications, such as Bulletin Board operation, when the full Transparent Mode features are not desired.

If CPACTIME is ON, characters are packetized and transmitted periodically as they are in Transparent Mode, but local editing and display features of Converse Mode are enabled, and software flow control may be used. For a discussion of how periodic packetizing works, see the command PACTIME, which controls the rate and mode of packet assembly.

You should set CR OFF in this mode, since otherwise the send-packet character will be inserted in the data being packetized even though it was not typed. In order to include <CR> characters in transmitted packets, set SENDPAC to a normally unused character (e.g., <CTRL-P>), at which point the TNC will treat <CR> as an ordinary character.

You can set CPACTIME ON for a mode of operation similar to full break-in CW, in which your text is transmitted soon after you type it, but in short bursts of a few characters, and the other station may break in at will. Some operators find it easier to carry on a conversation in this mode, since it eliminates the delays while long packets are being typed.

CR ON/OFF Mode: Packet Default: ON

Parameters:

ON The send-packet character, normally <CR>, is appended to all packets sent in Converse Mode.

OFF The send-packet character is not appended to packets.

When CR is ON, all packets sent in Converse Mode will include, as the last character of the packet, the send-packet character which forces the packet to be sent. If CR is OFF, the send- packet character is interpreted solely as a command to the MFJ-1278, not as data to be included in the packet, and furthermore, it will not be echoed to the terminal.

Setting CR ON and SENDPAC $0D results in a natural conversation mode. Each line is
