Re: Easy RS232?

I was staying away from the parallel port because I previously had a parallel port DAC device that required a driver be loaded. I want to keep this portable and not have to load the driver (and risk problems) on any PC. I looked up NTPORT (for Win NT) and it is apparently an add-in that will compile...

Re: Easy RS232?

Greg, thanks for your efforts.<p>It seems to me that the complexity is building to a level that I wanted (maybe unrealistically) to avoid. I was hoping for one chip with 8 parallel bit inputs and a pair of output pins that would directly interface with the serial port. It sounds like the UART interf...

Re: Easy RS232?

Thanks for the reply! I'll have to see if I can decipher what the chips require to operate. Can you tell me if the UART functions as a single chip binary to RS232 interface? In other words can I shift bits into it, and have it take care of all RS232 protocol requirements? I'll be using Visual BASIC ...

Easy RS232?

I'm building a 42 bit binary counter that I want to input to the serial port of a PC. The count will be in a shift register. Is there an easy way to get those 42 bits into the serial port of a PC? I was looking for a chip that I could shift the bits into and it would send it out RS232. Couldn't find...
