Re: How configure 991a and direwolf for ISS

Keith, Are you asking me? Or are you just replting to the wrong part of the thread?
I have never had an issue with PTT being stuck when using USB to TTL serial converters. I have used the DTech FTDI with the 6-pin header connector, several brands of the cheap CP2102 boards, and most recently tried one of the USB to UART/SPI/I2C boards (CH341A).? The board you choose must have "at least" the RTS/CTS pins.?
I typcially make sure they have all the serial interface pins so I have "lots of options".
On my Linux machines (Pi I use GPIO) I typically use /dev/ttyUSB# -RTS? where # is the USB device number.
Most often I use a udev rule to rename the device to make life easier.

Hmmm...what HAMLIB version are you
using?
Also, are you using feritte cores on
your USB cables, rig properly grounded, etc?? If not, the RF from
the rig can produce unpredictable operation.?

I was working off
physical serial port devices that I have used for PTT.?
I have used different USB
to serial TTL devices for PTT using FTDI or other chips.

I would go with Keith's
advice!
PTT
/dev/serial/by-id/usb-Silicon_Labs_CP2105_Dual_USB_to_UART_Bridge_Controller_00C98A2F-if01-port0
does not key the radio.
PTT
/dev/serial/by-id/usb-Silicon_Labs_CP2105_Dual_USB_to_UART_Bridge_Controller_00C98A2F-if01-port0
RTS keys, but does not unkey the radio.
