We changed from a kernel mode driver to user mode driver for the purpose of quality improvement and expansibility. It can control the USB/Ethernet connection device through the POS application program for the serial/parallel connection.ĭue to the addition of the virtual parallel port, the “TMCOMUSB” is changed (name change) to “TM Virtual Port Driver”. This is the driver to control the device, which is connected to the USB/Ethernet port, as the virtual serial port or virtual parallel port from the POS application program.
