Has anybody tried using a DB9 serial-to-USB adapter to get hardware lines into and out of the machine? I've been struggling to find a ready-made device complete with driver for Windows and have come up empty. I'm thinking of just overcoming my laziness and doing it myself. Perhaps the same thing could be done in a generic way in linux such that you hook the COR line from the radio to CTS line of the adapter, and PTT to the RTS line. When you diddle them on the USB interface, the DB9 asserts the corresponding pin and off you go. Since these adapters are in current production and demand, supply should not become a problem for a long time. They are smaller than the DB-25 parallel interface which is deprecated and would likely become harder to find as well. Bote

Hello Carl,
Yes, chan_usbradio and chan_simpleusb both support use of a parallel port. I don't believe the XIPAR project does.
I have had tremendous success using the parallel port for COS,PTT and AUX/GPIO on my nodes.
As you mentioned, the CM108 fobs are becoming harder to find, and some of us have great difficulty soldering to tiny SMT pins. While I have successfully modified CM108 fobs, I have destroyed two fobs in the process. ...

Hi group,
Carl M1ELR here, I noticed in a post a few days ago there was mention of using the Parallel port for PTT or COR, is this possible?
I currently run my node using the Centos install package from the Allstar site but can change to the install version from Xipar if needed.
I have without success been buying sound fobs to build a new interface and now have a drawer full of USB fobs that I can't mod, if the I/O wasn't via the USB sound fob that would make life so much easier as the CM108 seems to be getting harder to source.
Thanks,
Best Regards
