By lowering the baud rate you're now allowing device B (and SERIN2) twice the time to receive the bits and assemble the byte.
That's probably what's helping a lot more than any line noise issue.

Tumbleweed, I had very strong suspicions that the issues were in the communication lines. I changed the Baud rate from 19200 to 9600 and I haven't got anymore wrong data at the receiver. I remember...
Ioannis, yes I'm doing data validation checks all the time. The first byte of the array is always 174. If this condition is not met, then the reading is discarded.

The attach zip contains a number of projects, the clock application is called "Clock_8_BIT_par_TFT.pbp" This project has a external RTC that can be set via USB with VB6.
There are a few other projects to drive this display including a SPI interface.

Re: SERIN2 Receiving Wrong Data
The sending device has the typical 18F4550 USB setup and it is set to "Define OSC 48". The receiving device is set to "DEFINE OSC 16".
