[Tlf-devel] Re: TLF

[rein couperus PA0RCT]

Hello Saku,

tnx for the remarks... I copy this to the tlf mailing list, as I think it is 
also interesting for others.

At the moment the port situation  is as follows:

CW output via cwdaemon-0.4. This can be set to ttyS0, ttyS1, lp0 or lp1.
Although Linux is flexible enough for other ports, most common hardware is 
limited to 2 serial ports and 1 parallel port. (on laptops only 1 serial port 
and 1 parallel port).
If you look at tlf, you will se that you will need max. 2 serial ports (rig 
and packet) and 1 parallel port (for CW). There are no plans as yet for 2x 
rig control on 1 PC, as PC's are so cheap now that it is feasible to use 1 
for each rig. The networking concept of tlf is based on this paradigm.
If you use a separate pc for packet (most stations do) you can get packet info 
in via the network, so a laptop with 1 serial port and 1 parallel port will 
be enough.

At this moment it is too much work to support all this linux flexibility. If 
somebody from the community will volunteer, it is fine with me...
I am concentrating more on extending the flexibility of tlf at the moment..

I can agree with that.

Tlf handles only ttyS0 and ttyS1 for rig control at the moment (see above).
This can be extended in the future.

Tlf will output a PTT signal via cwdaemon in future. Like CT and TRlog (same 
pin, If I remember correctly Pin 14 on lp0). This is not yet ready. I will 
stop supporting the other keyers, to make maintenance of the package easier.
So your best bet is to use cwdaemon-0.4.
