A serial port may be useful, but some users have reported that the serial port message cannot be opened on their PC. This can be a big problem, and in today’s article we will show you how to solve it.
Problems with a serial port can be very annoying, especially if you tend to use the serial port frequently. When we talk about these types of problems, here are some related problems that have been reported by users:
- Connection to com1 Windows 10, com3 could not be opened – This problem can sometimes occur if you do not have the required drivers. To solve the problem, you must update the serial port driver and verify that it solves your problem.
- Putty cannot open Windows 10 serial port – Sometimes this problem can occur due to some Windows services. This is not a big problem, and you can solve it by disabling these services.
- Access to the serial interface com1 cannot be opened – This problem may occur due to problems with the serial interface. To solve the problem, temporarily disable the serial port and see if it helps.
- Com port cannot be opened win error code 5, 123, 32 – These are some common problems that can occur with a serial port, but you should be able to solve most of them with one of our solutions.
Windows may try to assign it to a COM port already in use. It seems that Windows sometimes gets an inconsistency in the registry of what has already been assigned.
To see if this is the problem (and if possible solve it), try changing the assigned COM port.
- Go to Device Manager > Ports (COM & LPT) > mbed Serial Port, then right-click and select Properties.
- Select the Port Settings tab and click Advanced.
- Under “COM port number”, try to select a different COM port.
January 2021 Update:
We now recommend using this tool for your error. Additionally, this tool fixes common computer errors, protects you against file loss, malware, hardware failures and optimizes your PC for maximum performance. You can fix your PC problems quickly and prevent others from happening with this software:
- Step 1 : Download PC Repair & Optimizer Tool (Windows 10, 8, 7, XP, Vista – Microsoft Gold Certified).
- Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
- Step 3 : Click “Repair All” to fix all issues.
Note that Windows marks some of them as (in use), but does not consider them exhaustive, for the same reason that this problem may exist!
Try switching it to a few different unused COM ports and see if it has an effect. If not, we will dive deeper to see what Windows is reporting.
And don’t forget to unplug the power cord after the change to recharge the driver and see all the results.
Try using another cable.
I noticed that using an older USB cable sometimes leads to a poor connection of the card. It would be moody if it worked sometimes and not differently. The problem was solved with a new or even different cable.
Hyperterminal
If you enter “Hyperterminal” in the Windows Start menu, right-click after the call and select “Run as administrator”. It should help you access the serial port.
Also check which COM port it uses. To do this, follow these steps:
1. press the window+R button
2. type devmgmt.msc
3. go to ports
Now check which port is assigned to the USE serial converter and use it in the spatula.

BERLIN, GERMANY (September 4, 2019) Today Acer announced its C250i portable LED wireless projector with stand-free multi-angle orientation and the world’s first[1] auto-portrait mode to provide users with an effortless way to share smartphone content anytime, anywhere. The Acer C250i is a super lightweight projector that packs a punch when it comes to multi-angle viewing, resolution, battery life, and overall ease of use.
“Acer continues to show innovation in the projector market with the C250i,” said Victor Chien, President, Digital Display Business, Acer Inc. “It not only features a creatively designed form factor that allows multi-angle projection without a stand or tripod, but also a unique auto-portrait mode for smartphone content sharing.”
Acer C250i: Multi-angle Projection Anytime, Anywhere
Unlike other projectors limited to horizontal throws, the C250i supports stand-free multi-angle projection thanks to its unique twisted roll design. This design is not only stylish, but saves space while offering users complete flexibility in projecting their screen onto walls, ceilings, and any surface they desire – without requiring a stand or tripod. Placed on its side, users can “roll” the projector to find the best angle for viewing content on the wall or ceiling; vertical orientation supports horizontal wall throws and activates the auto-portrait mode. This innovative auto-portrait mode lets users directly project portrait video chatting or live-streaming sessions (on Facebook or Instagram, for example) wirelessly, utilizing the full projection surface without black bars on the side. Created for ultimate flexibility and everyday use in mind, the C250i’s feature set is sure to impress even the most advanced smartphone users. Keystone correction guarantees on-screen content looks impeccable from every angle.
C250i: High-Quality Full HD Resolution and Wireless Performance
Despite its compact size, the C250i supports beautiful high-definition 1080p imagery and a battery life of up to 5 hours from a single charge. Both Android and iOS users can connect to the C250i wirelessly for an effortless, cable-free experience at home or on the road. The C250i’s LED module offers up to a 30,000-hour lifespan, a wide color gamut that is 100% NTSC-compatible, 300 ANSI lumens brightness, and a 5,000:1 contrast ratio. The C250i also serves as a portable power bank to recharge phones on the go. The projector’s built-in Bluetooth speakers are rated at 5 watts for best-in-class sound when watching movies or TV shows.
C250i: An Abundance of Connectivity Options
In addition to wireless connectivity, the Acer C250i also features a standard HDMI port for connecting and viewing content on a laptop or desktop computer. USB Type-C and Type-A ports support video-out for smartphones and PCs alike, and is 100% plug and play so no additional software or drivers are needed. The USB Type-A port allows direct multimedia playback from a USB drive for an incredibly sleek and PC-free projection experience.

In addition to the C250i, Acer also announced the new PL1 series laser projectors (PL1520i/PL1320W/PL1220), geared for medium-sized exhibition venues, events, tradeshows or meeting rooms. It is designed for 24/7, low-maintenance operation with an laser module that lasts up to 30,000 hours. The PL1 series projectors are ideal for projecting images wirelessly[2] in business applications such as advertising, community notice boards, video playback in lobbies and more. For added durability they are IP6X-rated with a sealed optical engine and support 360-degree and portrait projection[3] as well as 4-corner keystone image adjustment.
