| Jun 20 at 18:16 | comment | added | Ben Voigt | @Justme: The question isn't super specific on what type of serial port the other device needs -- it proposes to use RS-232 but it doesn't seem that has actually been done. Since I2C falls into the general category of "serial ports", I thought it worth mentioning, just in case OP re-reads the documentation on the device and finds it's an I2C serial connection needed, not UART. | |
| Jun 20 at 17:37 | comment | added | Justme | @BenVoigt Yes it does have DDC and what/how would it do to help passing UART at all? | |
| Jun 20 at 16:15 | comment | added | Ben Voigt | Note that the VGA and HDMI pinouts do have an embedded I2C link, called DDC | |

Some fixes.

| Jun 20 at 3:48 | comment | added | Justme | It is physically impossible for any of that to work. Unless the adapters are passive and only change the connector, not the data protocol. Simply use a USB serial adapter, but remember that in a production environment it may not be a reliable solution. | |

| Jun 20 at 1:55 | comment | added | Ben Leatherman | Yeah, I think that's going to be my first attempt. Honestly, I just was so perplexed about it picking up the device connected through an HDMI port, I just had to ask people smarter than me about this, hehe. | |
| Jun 20 at 1:18 | comment | added | Ben Leatherman | I believe they're Dell Optiplex Micros. He's somehow got his hands on a half dozen of them for about $150 or so each. Refurbs or something, but he pulls one out any time someone's like "I need a computer" and they're terrible. I should have clarified. They're x86 and they've got win10 installed. | |
| Jun 19 at 23:59 | comment | added | Peter Bennett | What are "these little microcomputers"? They may have serial ports, but with "TTL" levels rather than RS-232, and with pin headers rather than DE-9 connectors. If they have USB ports, the easy solution is a USB<->RS232 adaptor. | |
