1.1 Serial Port
On 6800 from Android the printer is accessible on "/dev/ttymxc4", which is RS-232 serial port
with HW flow control.
On 6800W from Windows the printer is accessible on "COM4", which is RS-232 serial port with
HW flow control. Printer is also accessible on “COM6”, which essentially is a USB CDC device and
is faster than “COM4”. Do not use both ports simultaneously.
1.2 Serial port settings
Printer operates with following settings on “COM4”:
- Baud rate: 38400 bit/s
- Data bits: 8
- Parity: none
- Stop bits: 1
- Flow control: RTS/CTS
For “COM6” settings are not relevant – it works with same high speed disregarding baud rate
etc.
