In the Modeling tab of the toolstrip, select Model Settings. In the Configuration Parameter dialog box, click Hardware Implementation. Set the Hardware board parameter to Android Device. How are your serial ports set up in the BIOS? These options can be found on page 2 of the System Setup screen.

Note that these will not change until the port is disconnected and connected again. The Serial Configuration block configures parameters for a serial port that you can use to send and receive data. You must set the parameters of your serial port before you set up the Serial Receive and the Serial Send block.

In Windows command prompt to configure a serial port, I can simple use:
or to read the configuration:
Are there similar commands in Linux? What would be the easiest way to find and configure the serial port in Linux?

You can use the
stty command to set such parameters.
This will show all settings on the first serial port (replace
ttyS0 with ttyUSB0 if using an USB serial port):
This will set the baud rate to 9600, 8 bits, 1 stop bit, no parity:
One thing that generally confuses people is that most serial drivers will reset the settings to the defaults once the device is closed (i.e. no process has the device open anymore). So the above
stty command will set the settings, then when it's done the driver resets them again. If you first have your POS software open the device and then perform the stty settings, they should stick around until your POS software closes the device again (e.g. upon exiting).
I'd have thought that the POS software should have some way of configuring these settings on its own. If you're writing your own software to drive the printer, make sure you first open the device, and then perform the
stty command.

You may also need to play around with other settings, e.g.
opost means that output postprocessing will be performed. If opost and onlcr are both set, the onlcr will cause an extra carriage return (0xd) to be added when a newline (0xa) byte is output, typically to prevent staircase printing such as
This may or may not be what you want. If you want a raw one-to-one output to the printer turn
opost off (add -opost to the stty parameters).
Handshaking (flow control) is also controlled with
stty , without knowing more about the printer I can't tell whether you need to set anything.
Check the wurtelwurtel
stty manpage for lots more info.
