The system uses RSID signalling to notify the link layer protocol engine of mode changes and also makes signal noise ratio data available to the application PTT signalling is generated by the client itself The client program is available for all operating systems Link layer protocol The PSKmail system uses a master slave protocol The server is the master the client is the slave In case two clients connect each other for a TTY chat session the caller is the slave All control functions are in the master which makes timing a lot easier than in the first PSKmail implementations where client and server would compete until they were transmitting synchronously on top of each other 62 Status diagram server Client Connect a Listening Connect ack Status msg oe Wekome Connected Session ea ct est esult Disconnect Transfer a status Au Transfer N Result ay QUIT Abort Disconnecting Protocol details All transactions between server and client are packed in frames Every frame consists of maximum 18 blocks viz O 16 data blocks 1 status block and 1 optional identification block at start of session and every 10 minutes thereafter Frame structure lt SOH gt lt ident block gt lt data block gt lt data block gt lt status block gt lt EOT gt All blocks have the same structure They contain a header a data partition and a CRC16 number The start of a block is marked with a lt SOH
