2. Any chance to fix the missing HW flow control on the modem UART connection?
(Is this the source of the "W (541151) cellular: UART hw fifo overflow" I see periodically?)
Yes, and you'll often see "gsm-mux: Frame error: EOF mismatch" log lines in combination with these. I also added counters for these, you can query them with the "simcom status debug" command:
OVMS# sim stat deb Network Registration: RegisteredHome Provider: congstar Signal: -97 dBm
State: NetMode Ticker: 73099 User Data: 0 *** HW FIFO overflows: 21* Buffer overflows: 0
Mux Status: up Open Channels: 4 *** Framing Errors: 24* Last RX frame: 1 sec(s) ago RX frames: 151452 TX frames: 5472
PPP: Connected on channel: #2
