https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D278716 --- Comment #1 from O. Hartmann <ohartmann@walstatt.org> --- Addendum: I ordered ESP32 with CH340 UART to verify my observations with uslcom(4) and CP2102 or CP2104 UARTs on devices I use. I'll report. Also I'm inclined to install a Lenovo T560 notebook with FBSD 13.2, 14.0 and 14.1-PRERELEASE to check, whether the problem persists and were the "terminator" might reside. In the meanwhile I tried to move to Linux, Xubuntu 24.04 LTS to be specific= and used the convenient ESP-IDF installation for quick testing. Using the very same cabling, ESP32s test platforms, Xubuntu had out of 20 attempts of connections with esptool (taken from the IDF 5.1.3, which seems= to be 4.7.0 as the FreeBSD's port) one failure on the hardware platform Lenovo T560 to connect. In all other cases connection was established. My skills regarding FreeBSD's internal serial system are very limited, but = if I can provide some more details while setting up the test platforms please contact me - and be patient, try to get to it as soon as possible. --=20 You are receiving this mail because: You are the assignee for the bug.=
