WebAug 13, 2024 · Matching port speed (using stty) and GPS speed (using gpsinit) works up to 115,200, but only until power cycle, when the GPS retains the new speed but /dev/ttyAMA1 goes back to default.

WebAug 9, 2024 · In the specification of RS232C which is generally called a serial port, the maximum speed is 20Kbps. Typical interface ICs are often used up to 115.2Kbps, but more than that will depend on the hardware and device driver vendor's mindset.
