I wonder if using a USB to serial adapter would work well in linux. It
worked well when I was a mac user. I wanted to experiment with using
fldigi, but my laptop only has USB which is common for new machines.
It seems like serial ports are going bye bye.
I've used some of them and they worked for me and my FC6 without any
special driver.

I have a software I like to use called gmfsk which uses the serial
port to turn on and off the transmitter in my radio. It worked fine on
my old computer. Now when I try to run gmfsk it puts up an error panel
that says "Not a serial or parallel port". This made me think the new
computer which has a serial port that is not working.
With a volt meter I find some pins have a constant -10.7 volts on
them which is the standard RS-232 for a no-data signal. In this static
measure the voltmeter sees no positive volts near +12 volts.
Wanting a way to test the serial port I recalled minicom and after
getting it set up on /dev/ttyS0 it seems happy with Com 1. The old
/dev/modem is gone on F7. But now what is a way to drive the serial port
pins to a constant plus voltage with minicom?
I have a scope that I can use if there are no way to make a constant
positive voltage. My fear is that the serial port is broken and can't
make a positive voltage.

I do have a usb to serial device but it didn't seem to work with F7.
It works fine with windows XP. On this computer I have a REAL serial
port that does not seem to work.
