PACKET11Monitoring and Calling CQIf you turn the MONITOR command ON, you will begin to see other people's packets on yourscreen. You will notice two callsigns at the beginning of each packet separated by a >. The firstcallsign is the station the packet is from. And the second callsign is the station the packet is to. AnUnproto packet may have a name or CQ for the second callsign.To set what what will be seen as the "to" callsign of an Unproto packet, you use the the UNPROTOcommand. This comes default as CQ, but if you wanted to put in your name instead, you would besure you are in Command Mode and issue a command similar to this:unamewhere u is short for unproto,name is your name and is the return or enter key on yourcomputer keyboard. In order to call CQ you must get into the Convers Mode, so that what you aretyping to the TNC will be interpreted as data to be sent out on the air and not as commands. Todo this, type:kor, if you have a version earlier than 2.84, this shortcut is not available and you must type:convNow anything you will be packetized and sent out on the air. Remember to get back to CommandMode you enter a Ctrl-C (default) by holding down the control key while pressing c. You will begoing between Command and Convers Mode depending on if you want to talk to the TNC or havethe TNC packetize what you type to go out on the air.A Simple ConnectOnce you see a station you would like to connect to, be sure you are in Command Mode, and issuea connect request, example:ccallsignwhere c is short for connect andcallsign is the callsign of the station you wish to connect to. If forany reason the connection fails, the TNC will send the following message to your screen:*** RETRY COUNT EXCEEDED*** DISCONNECTEDWhen your TNC does receive an acknowledgment for a connect packet it will display a message onyour screen like:*** CONNECTED TO callsignand your TNC will change to the Converse Mode (dependent on setting of NOMODE andCONMODE). Now what you type will be interpreted by the TNC as data to be sent to the other sta-tion and not commands to the TNC. The MCON parameter comes defaulted to OFF. Therefore onceyou are connected all you will see is what you type and what the other person sends you. Anypackets sent by other people will not be monitored.Two things determine when the data will be packetized. One is the parameter SENDPAC. This isdefaulted as the return or enter key you are telling the TNC to make a new packet. A second pa-rameter, PACLEN, determines the maximum length of any packet. If you enter data longer thanthis length, a packet will be made even though you have not pressed the return or enter key.
