unable to get agetty to work at 115200 baud - Raspberry Pi Forums

-

i have rpi3b , i'm running raspbian stretch.

goal login via usb-to-serial adapter using ssh @ 115200. working @ 9600. when attempt login @ 115200, no prompt appears. ssh session blank.

have done following:

0. apt-get update, apt-get upgrade, apt-get dist-update done.
1. /boot/config.txt contains enable_uart=1
2. agetty used service: execstart=-/sbin/agetty --keep-baud 115200,38400,9600 %i $term
3. /dev/ttyusb0 explicitly set 115200: sudo stty -f /dev/ttyusb0 115200
4. know /dev/ttyusb0 working @ 115200 because if connect minicom /dev/ttyusb0, can send , receive characters @ 115200.

ideas solution or next step?

regards,radiokk6

Valutazione Template - Joomla! Forum - community, help and support

salve, prima di installare joomla, vorrei porvi tre semplici domande: 1) l'ultima versione in italiano di joomla, supporta questo template prodotto da gavik? loro scrivono che non è un semplice template, ma una vera e propria suite, ma vorrei una vostra opinione. qui sono descritte le funzioni della suite. 2) per sfruttare gli elementi che si vedono nella pagina, ad esempio quello in alto sinistra dove scorrono le notizie, occorre installare qualche componente aggiuntivo? 3) futuri upgrade alla piattaforma joomla, potranno inficiare il funzionamento o la compatibilità del template? vi ringrazio anticipatamente della disponibilità. 1) non vedo nulla di particolare se non una miriade di posizioni per blocchi 2) è un modulo se non sbaglio pagamento, ma adesso non ricordo bene 3) no. ti ricordo che devi installare joomla  1.0.12 Board index Joomla!

SD Datastring Convention

i wondering if there preferred convention appending data logged?  see standard sd example uses: code: [select] void loop() {   // make string assembling data log:   string datastring = "";   // read 3 sensors , append string:   (int analogpin = 0; analogpin < 3; analogpin++) {     int sensor = analogread(analogpin);     datastring += string(sensor);     if (analogpin < 2) {       datastring += ",";     }   } creating string called datastring, , appending it, have seen in forums string not liked.  around this, code data logging looks this: code: [select] void sdupdate() {   datetime = rtc.now();   unsigned int hour = now.hour();   unsigned int minute = now.minute();   unsigned int second = now.second();   char datastring[100] = "";   char char_current_pay[15] = "";   char char_overall_pay[15] = ""; ...
