Hi John, I am not aware of a graphical tool to do this, although it may exist. Open a shell (terminal) window and try a couple of commands: ls -l /dev/ttyS* This will list the serial ports that linux has defined. It will also be useful in permissions questions. For each port listed, try the command: echo hellohello > /dev/ttyS0 but modify the zero for each numbered port. BTW the first port (/dev/ttyS0) is like com1 in Windows. The responses tell you a lot... if the port is there and working you will see no error, it will send the hellohello to the port. If the port does not exist you should see a message about an i/o error. If you do not have permission to use the port you should see a message that you do not have permission to write to the port. Let us know what you find. Howard K5HB PS: in case you are not familiar with it there is a great package manager tool called Synaptic under the System - Administration menu. This would get you a much improved fldigi. ----- Original Message ---- From: "acjohn1@xxxxxxxx" <acjohn1@xxxxxxxx> To: pskmail@xxxxxxxxxxxxx Sent: Wednesday, May 28, 2008 11:00:06 AM Subject: [pskmail] Re: port address Linux Hello Alan Thanks for the return. I have been going around and around trying to get this thing working. I tried to download FLDIGI through the program downloader but it would not open due to a corrupt file. I am brand new to Linux and it has been diferent. I realy didn't have any trouble down loading this version of FLDIGI and it is decoding okay but I can not get the com port to key the Buxcom interface. I did make sure the comports are there and on in BIOs and I even found the com ports in Ubuntu but do not know what to put into the address box in configure menu and not sure that the ports are turned on. I actualy swaped for this computer to run the whole PSKMAIL sweet of programs. It is a older composet of parts. I am not much of a programer but If you can give me a string of menus I can fallow. Thanks 73 John Rusmiselle KG4VHV ____________________________________________________________ Click here for great computer networking solutions! http://thirdpartyoffers.juno.com/TGL2141/fc/Ioyw6i3oHgM9KUJARX8R6DT0hGun5cLoEu5VWcGsk0L3aRgQKDwgqU/
