After days and days of trying to get my Serial to USB to work I am no further forward - I am trying to log NMEA sentences from a GPS Module via USB to Serial.
I have two leads:
Bus 001 Device 010: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port
Bus 001 Device 011: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter
and both work on a Windows XP machine, which is frustrating to say the least.
When I try on my Pi I receive garbled text no matter what speed/parity/stopbits I choose. I am using Minicom to see the incoming data.
I have read, and tried solutions therein, many reports on various forums without making any progress. I'm beginning to doubt my sanity!
Does anyone have any idea however bizarre it might seem that might help me? Serial comms is not difficult but I seem to have come up against a brick wall.
