If you’re holding this card, you likely need to revive legacy industrial equipment (CNC, printers, EPROM programmers, or POS systems) on a modern PC without native LPT or COM ports. The WCH chipset is the go-to solution for this job. However, the cryptic model string ("PS-T-PS------- L -X--") suggests a generic OEM version—so quality varies, but the core silicon is solid.
Note to manufacturer: Please, for the love of legacy hardware, add a clear model label and a driver QR code. “PS-T-PS------- L -X--” is not a model number – it’s a cat walked on the keyboard. Driver WCH PCI Express PS-T-PS------- L -X--
Given the fragmented label, this review assumes the device is a (often seen as "PCIe to 2S/1P" or similar). Review: WCH PCI Express Card (Model: PS-T-PS...) Rating: ⭐⭐⭐⭐ (4/5) – Great hardware, temperamental driver setup. If you’re holding this card, you likely need
You need a real hardware LPT/COM port for CNC, debugging, or retro computing. Skip if: You just need a printer or one serial device – get a USB adapter instead. Note to manufacturer: Please, for the love of
