[Tlf-devel] Re: USB, success!

[rein couperus PA0R]

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...
