I installed Microsoft POS for .NET 1.14.1 and installed the EPSON OPOS ADK for .NET. I used the OPOS ADK setup and checked "USB" and "Serial" check boxes and created 2 configurations; one for the USB and one for the Serial Port. In the "Serial" setup, I know I have placed the right values since those values came from the printer itself. Using the USB port, I don't get any problems but when I transfer the printer's connection to serial port and using the "CheckHealth", I get this message
ErrorCode: 111
ErrorCodeExtended: 0
Message: It is not Initialized
I know that my serial cable is working because I have tested it on other devices.

I am using SIM7600 module with Beaglebone board connected thru UART2. It works well with ppp on /dev/ttyS2.
Since the application wants the GPS info simultaneously, trying to use CMUX with the n_gsm driver as given here
https://github.com/Rtone/cmux
The modem responds with OK for AT+CMUX=0,0,5,127,0,0,200.
The tty devices for the virtual ports 1 to 4 are created in the linux - /dev/ttyGSM[1-4].
But no serial port utilities work.
Anyone has any experience in this.
I've got my sim900 module working with arduino by using their software serial library, however, I want to eliminate arduino from the equation and have serial communication directly to sim900 module.
I'm using putty as my terminal emulator. It's serial is configured to COM1 19200 8 N 1 the same as device manager configuration for this port.
I connect straight from hardware serial on my PCs motherboard into serial-to-ttl interface board which connects to sim900 module. The board has 4 pins - VCC GND TX RX. They're all connected to my sim900 hardware serial as follows: VCC=5V GND=GND TX=TX RX=RX (Yes I know that it's always actually TX=RX and RX=TX, but when I connect it that way my interface board doesn't blink any led to indicate a transfer whereas it does when I connect TX=TX and RX=RX). The switch on the module is set to hardware serial pins as well.
So the only thing that happens when I send AT commands such as AT or ATI and press enter is that puttys cursor comes back to the beginning of command that I typed. No response.
I'm thinking that I'm not doing something that the arduinos software serial port is doing when it sends commands to sim900.
Can anyone help please ? It's literally been days of trying different configurations with no results.
In that time besides getting sim900 working with arduino software serial I verified that the hardware serial port on my motherboard is working correctly and the interface board is working correctly as well.
I've been trying to test a FT201XQ USB-I2C breakout board: UMFT201XB-01, so I can connect it to a master device such as an Arduino and sniff what that device is sending through I2C.
To see the output of the slave device I have successfully configured a Virtual COM PORT by installing the D2XX drivers provided by ftdchip.com. I can open the serial port through puTTY and everything seems fine in that regard.
Then, i've loaded the "master_writer" example on my Arduino, which sends 1 byte at a time to an address (0x22 is specified in the UM201XB-01 datasheet as the default address).
Nothing seems to happen in the COM port that i've earlier opened. Do I need to configure/program the FTDI device in some way? In that case, how can I do it, in a general way?

Thank you in advance, and sorry if this is a "noob" question : P
Background
I am trying to connect to a serial GSM - modem of Wavecom type.
I was able to communicate with the modem using the guide
http://www.easysw.com/~mike/serial/serial.html
on my Ubuntu machine.
but when I tried to connect it through a device with serial port and running on Linux kernel Linux 2.6.14.7-tiny1-WR1.3al_small I get junk data returned. I have tried all of the baud values to connect to the modem. It connected on 115200 baud value when it was working, but the same value does not work from this Kernel. Its a ARM target machine. note : I cross compiled the code for ARM
Question
Do I need a driver for a modem to just be connected through a serial terminal Program ?
Please make sure that the RS232/TTL converter of your ARM board is working correctly. for example you can connect it to your Ubuntu machine at first and transmit something with a terminal program.
question : 1 ) Do i need a driver for Modem to just be connected through a Serial Terminal Program ?
No.You can connect to your GSM modem simply by having a serial port and a terminal program.
I bought this magnetic strip reader writer (MSRE106) and I use USB adapter to connect it to my laptop because I have no serial port in my computer. But now I have a problem since the software of the device recognizes only serial ports on windows. After looking up I found someone that wrote a python script for Linux (found here The Script).
Still even in this python script in the settings file it has this variable
## Com port.
COM = "COM1"
How can I change this to be one of my USB ports instead of a serial one because I have none
This script is made to use serial port as well, which means you can't just modify COM="USB1" or whatever to use your USB adapter. If you have a look at line 264 a serial port is open using function SerialPort().
To fix this issue you must install your USB adapter's driver that will emulate a serial port and create a fake COM1 you can use with this script or the original software of the MSRE106.
