The PL2303 is produced by a Taiwanese company, but has been used very successfully and is a decent product. Additionally if the bus is busy, receiving data could end up overflowing the internal buffers of the chip and cause data loss.īUT that all being said, they work but under some conditions they don't work prefectly. Since every access has to go across this bus and serial is bursty at best, it can mean that data stutters on the output side. Acquisition of the USB bus can take as long as 50us, and that's a long time. The USB bus has some latency issues that can cause the USB devices to hick up. The same is all true in the reverse direction. The chip then takes the data, buffers it, and shifts it out serially either with flow control or without. Then it takes the raw data and sends it to the chip via USB. The code is designed to mimmic it, and all the settings. How they work is simple, the driver makes it look like a standard communications port. I current use one in a product my company sells and it does a dandy job in Windows but kinda stinks for linux and mac.

Your options for free terminal emulators that can communicate via RS-232 (serial line) are extremely limited. Emulators that are capable of serial line communication are few and far between because most are now TCP/IP-exclusive. Click to expand.There aren't a lot of options for terminal emulators because it isn't 1989 anymore.
