What should be my tnc settings?
Your tnc should be set to terminal mode, 8 data bits, 1 stop bit and no parity. Most tnc’s are set up that way by default. You NEED to set MSTAMP, HEADERLN and MCOM(not MCON!) to off. Recommended baud rate is 9600. If you change the baud rate of your tnc, make sure you choose the same rate in aprspoint connect dialog.
