I've been trying to get a Pl2303 usb/serial cable to work reliably, but its dropping data @ 9600baud (8n1). I want to compare it to a known reliable solution to determine if the problem is with the PL2303 reliability. I have the HX/HXA prolific chipset.
The PICkit 2 GUI has the UART emulator and logic tool/analyzer. But a quick search of Microchip's website doesn't show a trace of it. They have been trying to kill off the PICkit 2 for a number of years but the PICkit 3 doesn't have the great additional tools.
We should make a sticky with the PK2 LA and serial tool code.
They also sold a version of the PK2, I think it was white, with code to generate stimulus and maybe debug I2C and maybe others. We should collect that and put it there tool
Here is the source code for all Pickit2 versions

BTW ..the UART tool works fine as a TTL rs232 device over usb. Xmitted data @ 9600 baud from a PIC USART. Logged to txt file , imported to Excel CSV. No probs.!
