So Skimask, am I correct to understand that hyperterminal will read the TTL signl OK if everything else is OK?

I'm not even sure if hypertermnal will read a TTL input or if TTL is intended for other types of devices.

I was trying to determine if the only code change I needed when using the 1K resistor instead of the MAX232 was to change the Serout command from the T prefix to the N prefix.


I programmed the PIC and ran it in the LabX-1 board. Blinking LEDs, output to a LCD, and rs232 output to hyperterminal. I used this to make sure the program was working properly. I then removed to PIC and inserted it into the board without the MAX232. The board without the MAx232 is a Picproto64 from microEngineering Labs. The only thing I added to the board was the 1K resistor between the RS232 transmit pin and the DB9. (I saw this on page 139 of the PicBasic Pro Compiler book.) I was trying to only add one new item at a time by testing the program out first on a purchased board. The components i put on the board without the MAX232 were a kit I purchased with the baord from microengineering Labs. The osc is 4MHz.


skimask, thanks for taking the time to reply. This is my first non-basicstamp project, so I appreciate the replies.
