 ===== QtSoundModem Settings =====
-**NOTE: The new NinoTNC 3600 bps mode does not yet work with QtSoundModem, but compatibility is being worked on! Unfortunately the 2400 bps mode mentioned below will no longer work with the node.**
+If using [[https://www.cantab.net/users/john.wiseman/Documents/QtSoundModem.html|QtSoundModem]] as a modem, you should select "QPSK AX.25 3600bd" and a centre frequency of 1650 hz.

 And in the modem settings (Settings -> Setup Modems) enable FX25 and IL2P for RX+TX, and tick the CRC box.

 ===== AX.25 2.2 with SREJ =====

+It is also possible to connect using AX.25 2.2, which may have some advantages described below.
 To do this from a BPQ node, use the "nc" (new connect) command, rather than the more common "c" (or "connect") command, and force L2 (no NET/ROM) by putting an exclamation mark in front of the callsign. E.g.:
@@ Line 59: / Line 57: @@
 One advantage of this type of connection is the ability for SREJ, or selective reject, to be used. Normally, several packet may be sent out in order, and if one of them is not received correctly the entire batch is rejected with a REJ message. The whole set of packets then has to be retransmitted. SREJ allows only specific packets to be rejected, so only those individual packet need to be retransmitted.
+As of BPQ version 6.0.24.69, netrom L4 connections will use AX.25 2.2 for the underlying L2 connection, with all the SREJ benefits without you having to do anything else.
