Rein, have you given thought to the DCE rpc interface? although, could see where it would have to have the linux DCE src installed on each system. it's a very rich client/server rpc. believe the src is still available, only in C lang. at one time, believe the military has a radio system based on DCE. eddie --- On Sun, 9/28/08, Rein Couperus <rein@xxxxxxxxxxxx> wrote: From: Rein Couperus <rein@xxxxxxxxxxxx> Subject: [pskmail] TCP interface for fldigi To: pskmail@xxxxxxxxxxxxx Cc: dl0ima@xxxxxxxxxxxxxx, w1hkj@xxxxxxxxx Date: Sunday, September 28, 2008, 2:31 AM I have decided to drop the POSIX SysV interace and go to the tcp/ip interface between fldigi and pskmail. There are 2 reasons for that, the main reason being that POSIX SysV is not available on window$ and Dave wants to drop it. Now that Intermar has decided to fork a window$ version of pskmail it makes even more sense. It also puts an end to the problems I have with the perl SysV implementation. There is also a xmlrpc interface but that is a lot heavier and we are looking to make the system leaner and meaner :) Dave has made changes to the tcp interface to enable Modem type control, which is available in fldigi version 3.04AC. I have made a small testing program to develop the interface in pskmail. That is now working, so I can build it into the client and server. There is one shop stopper at the moment: when I change the modem type the TX frequency lock (Lk button) is released. Which prevents using it on a scanning server. But I am sure this can be changed... Easiest would be if fldigi always locks the TX frequency to the sweet spot if sweet spot is enabled! Have a nice sunday!
