hi,

i've got a simple PBPro routine to send basic ASCII commands via RS232 to another embedded device. i'm running a 12f675 at 4MHz (internal osc) and communicating at 300bps 8N2. everything is working properly - the LED blinks, LCD displays, and i've confirmed that a PC can see the ASCII as expected.

my problem is that the other embedded device doesn't react to the PIC. if i send the same ASCII with my PC (same settings), the embedded device reacts. could it be that my PIC isn't putting out enough voltage? i'm not using anything to give true CMOS voltage levels - just 0 and +5V output. this has always been enough before on other projects, but this dude isn't responding.

any similar experiences out there?

thanks!
Pat
