If however you type "32" what are you sending? The string '32' - i.e two bytes representing the character 3 and the character 2, or the value '32' in one binary byte ...
MicroCode studio always send ASCII. So if you type 32, you'll send 2 bytes, 1 for 3 and 1 for 2. If you want to send 32 you must press and hold ALT and type 32 on your numeric keypad and release ALT. now you will send ASCII 32 in one shot.

the result in your receiver/transmitter will be different depending of wich modifier you'll use in the SERIN/SEROUT statement. The best way to get good idea, try within MicroCode Studio serial comm windows. HyperTerminal or between 2 PIC and LCDs if you have in stock...PORT pin can be also use with LEDs to see results.
