Strange problem with Serin/Serout on 16F628

[Bruce]

How do you know that you're not transmitting data to the player?

Have you looked at the tx output with a scope? Have you tried inverted mode?

Could be your player requires inverted serial. That would explain why it isn't responding.

Edit: You show @ DEVICE HS_OSC but you don't show any DEFINE OSC. If you're using
anything other than 4MHz, you'll want to define that oscillator speed. PBP assumes 4MHz
unless you specify otherwise, and that will for sure screw-the-pooch with timing if you're
not using a 4MHz osc. If you are using a 4MHz osc, you may want to switch to @ DEVICE
XT_OSC so you're not over-driving your 4MHz osc.
