Thermal Printer Serial Port C

Works for my use case connecting to the serial port on a router.

No-nonsense serial port. Works fine

Having equipment with serial ports and computers with none, I turned to a 4 port adapter from BH.

My company uses various serial devices, and most computers don't have serial ports anymore. Some USB/serial devices don't allow all software to communicate, even though they appear to be set up correctly. This device works perfectly every time, and even remembers what COM port number it was when it gets unplugged and plugged into a different USB port.

Used to interface a serial port multiplexer w/ a new USB only computer. It was plug and play after adjusting baud rate.

I bought this adapter to use a serial port on my laptop, for use with my weather station with my laptop. It functioned perfectly and allowed me to provide weather information. If your computer has a USB port but lacks an RS232 port then this is for you!

For those few times left you need a serial cable, and you don't have a computer built after 1995 (well, an old one, anyway), there's this guy/gal/cable. It works, the drivers installed flawlessly, the cable did its job, and I was able to lie to terminal software and tell it that a USB port was a serial port. YAY!

I recently damaged my laptop serial port. Rather than replace the laptop I bought a USA 19HS. This is a USB to serial connection. I connects with every PLC I program, first time, every time. I have equipped all my laptops USA 19HS adapters. I love the reliability.

I needed a serial port on a new Windows 7 (64bit) machine. This usb serial adapter did the job with no problems. It installed as COM3 but I needed either COM1 or COM2 due to application limitations. The instructions showed how to resolve this and make the configuration change and all worked fine.

I have an older Tripp Lite online UPS that only has a serial port for the interface. This adapter allowed me to communicate with the UPS over USB. I did have an install problem, but Tripp Lite tech support walked me through the driver config and all is well. PS: And Tech Support was a real person on the phone... amazing in this day, and to be commended.
