[chirp_users] CI-V port flow control RTS on DigiRig

[K5CG]

I opened a bug here [ https://chirp.danplanet.com/issues/10510?tab=history | https://chirp.danplanet.com/issues/10510?tab=history ] . 

I don't like the bug tracking system. Dan closed the ticket without allowing any further discussion or addition of additional evidence and I find it rude and frustrating. github.com and other issue tracking systems allow comments even after an issue is closed without changing the status of the issue. 

Regarding this part: "If RTS or DTR are getting set, it's not because CHIRP is asking for it... But, since CHIRP is already requesting neither assertion, there's nothing more it can do." 

Icom Memory Manager v1.1.0.14 can read the radio memories and it does not asset RTS unless you tell it to in the app - same USB serial port - Silicon Labs device driver. 

Perhaps CHIRP NEXT is not "asking" for RTS but it is being turned on when CHIRP runs anyway. That could be because it is not specified so could be the USB driver turns it on by default if not specified. 

Perhaps a toggle on the CHIRP Radio connect dialog to specifically set it low would work?

Isn't this something you would set in device manager for the port you are connecting to your radio? 
Try searching for "device manager", then examine the serial port connected to the radio by right-clicking on it and changing the port settings...

Hello all, 

I am not new to CHIRP but I'm setting up a new laptop and trying to manage memories on a (new to me) IC-7000. 

I am using a DigiRig radio interface which has a built in sound card, CI-V port and uses RTS of the same COM port to key PTT. 

When CHIRP Next 20230409 reads the radio it asserts RTS on the serial port which keys the transmitter. 

RTS nor DTR are needed for CI-V so CHIRP should not assume that the port requires flow control. This should be the default for all CI-V based radios but a pair of checkboxes on the initial READ RADIO dialog to disable either RTS or DTR or both would also solve this issue. 

I don't see a configuration dialog where port parameters can be changed. 

In the meantime I can disconnect the 13 pin accessory connector on the back of the radio to prevent it from keying.
