 ### TCP
 The latest additions to the Hamlib network control family are the [TCP](http://en.wikipedia.org/wiki/Transmission_Control_Protocol) based **rigctld** and **rotctld** daemons. The command set used by these daemons are simple text commands sent as ASCII strings. The commands are shared with the **rigctl** and **rotctl** test programs (with a couple of additions specific to the daemons). These daemons offer the latest in flexibility for applications using Hamlib.

 There are PDF files of each utility available for ease of viewing and printing.
 
 The TCP daemons allow connections from multiple applications simultaneously. For example, here at N0NB I am using Fldigi and CQRlog with **rigctld**.
