hi irmus,
try this
serout PORTB.2,4,[$A0]

if this ones work, that mean you not declare :

INCLUDE "modedefs.bas" at the begining of your program

It appear that in some case that you must write PORTB.x in uppercase too.

Try also this :
DEFINE CHAR_PACING 1000

if this is not working tell me which PIC you use and how it is connected to RS-232 (with in serie resistor, thru an Max232...)


let us know !!!

regards

I am using modedefs.bas . 4 - here it mode baudrate? I use max232 and pic16f84
Thanks

[mister_e]

when you don't include modedefs.bas SEROUT serpin,4,... is the same as SEROUT serpin,N2400...


what is your taget device to receive $a0 ???
$a0= 160 (decimal) = BLANK character in ASCII table

maybe this is why.

try PORTB.2,n2400,["hello ",#10,10,13]

it suppose to display hello 10

let me know

One other thing,
it also seems that SEROUT don't understand $ before data. Only #.

in your case if you really want to send $a0 use a variable

ToSend var byte
ToSend=$a0

SEROUT PORTB.2,4,[ToSend]

or
SEROUT PORTB.2,4,[#ToSend] ; output will be 160

I use comlite software and i can to see what i send to comport and what data receive from computer.
Thanks, i try this SEROUT PORTB.2,4,[#ToSend] ; output will be 160
