some days I hate pic's (serout,gsm,usb,f88)

Ok so at least you never opened the PIC16F88 datasheet and discover what's multiplexed on PORTA and if it's enable by default? Right?

Once done, you'll know why.

I read the picbasic manual instead, it said if thou use that pin for serial, it shalt do serial.

Which it does, but just not as efficiently, and only to some devices...........


If I set the port pin high with a high command, I get the same voltage on the pin as any other I set high, I dont have to worry about whats multiplexed on it / other uses it has, so why should the serout command not set everything up also?

In the manual little notes are included about other pic's with ''odd'' behaviour so I just presumed this had none to worry about.

it's not odd or curious.. it's normal. You're working with digital signal on analog by default I/o.

Open the PIC16F88 datasheet and discover the Analog section... section 12.0 and 13.0.

Now you need to disable the analog stuff
section 12.0 register 12-1 ANSEL:
ANSEL=0 ' set all related i/o to digital mode

Section 13.0 register 13-1 CMCON (and figure 13-1)
CMCON=7 ' Disable analog comparator

ok those comparator are already disabled by add the line just for safety sake

So add
ANSEL=0
CMCON=7
at the top of your code.
About now?
