There are several usb-to-serial adapter chip manufacturer, some legal and some not-so-legal (cloned), be sure to install the appropriate driver that match the chipset.

Command line is good

java was found, jar file was found and the proper command selected

Serial port found and opened

File data was transferred to the transmit buffer and accepted by the JSerialComm library to be transmitted asynchronously.

Exception: TimeoutException [message: wait-time > 60000 milliseconds]

For some reason the low level driver (written in C) of the JSerialComm library was not able to asynchronously send the data from the transmit buffer to the serial port driver, hence the TimeoutException message a little more than a minute after the Sending message.

This point to either a problematic usb-to-serial adapter or more probably a driver not matching the usb-to-serial adapter chipset.
