Good evening Wilbert,
thanks for the testing, I will upload a new version on sunday including the
changes. If I read the TRlog mailing list the USB capability is a hot issue.
Can you explain what is additionally needed to make it work (drivers,
hardware)? Would this also be possible for the LPT (CWdaemon)?
For tlf-0.9.3 I have done the same for the TNC port, that will also work with
TNCPORT=/dev/ttyUSBx.
Would appreciate if you could test that also some time next week...
Agn, tnx for the help!
Have a nice weekend....

P.S.: The transceive mode CT uses was the cause of several network crashes
during our cqww-cw at CT9L last year. Every time an op spun the dial of the
FT1000MP the network was flooded with freq. update packets, and the DOS
systems crashed. Once all 3 at the same time :-) This meant rebooting the
computers...
