Thanks Steve,Valentin,
I found reference to max3232 but sure that will not be available in my part of the world.How about Transistor level shifter? Regards It seems the Communists have pretty much destroyed Kolkata and West Bengal industries, but surely you can get from other parts of India RS232 level shifters which work on ~3V. Try Farnel India. Some shops in Bombay and Bangalore supply components on COD basis. Will hunt out their names and addresses if Farnell cannot supply. |

| RS232/serial port of PC for 3 volt microcontrollers | 01/01/70 00:00 | |
| No | 01/01/70 00:00 | |
| Try searching for: MAX3232 or SP3232 | 01/01/70 00:00 | |
| Transistor level shifter | 01/01/70 00:00 | |
| Availability | 01/01/70 00:00 | |
| only if you have +-12V | 01/01/70 00:00 | |
| For transistor based RS232 | 01/01/70 00:00 | |
| Bad idea! | 01/01/70 00:00 | |
| why do these 'maybe' circuits keep popping up? | 01/01/70 00:00 | |
| Few designs have suitable +/- supplies | 01/01/70 00:00 | |
| More to it than just voltages | 01/01/70 00:00 | |
| Yes of course | 01/01/70 00:00 | |
| because they do mostly "work" most of the time | 01/01/70 00:00 | |
| 'mostly' is never stated | 01/01/70 00:00 | |
| I suspect that it's actually quite high... | 01/01/70 00:00 | |
| If he had the supplies ... | 01/01/70 00:00 | |
| Get from other parts of India | 01/01/70 00:00 | |
| Why would you want to use one of those? | 01/01/70 00:00 | |
| Whats Your preference 3V RS or AT89c2051? | 01/01/70 00:00 | |
| If it's specifically for a PC, is RS232 a good choice? | 01/01/70 00:00 | |
