character format

BernardJP

Hello,
I'm expecting to drive a system under format : 9600 bauds, 8 data bits, one even parity bit, 2 stop bits.
As you know, BS2sx give 2 possibilities : 8 data bits, no parity or 7 data bits, one even parity.
How can we solve that, except to use an external UART to manage conversion between formats ?
Best Regards,
BernardJP

Yup, external UART. And no MAXIM 3100 either, it has the same limitations as the BS2.

One other approach is to write your own, simple PIC formatter, which does all the formats you want -- which you'll need to write in PIC assembly language.

Another approach is to get the SX/B, set up the command, then tweak the bits and bit-counts to get the parity you want.

An assembler source for the SX28 using a uart with 7/8 data, odd/even/none parity, 1/2 stopbits can be found here:

Wow, Peter that's excellent.

I would like to thank you, Allan and now Peter, for your perfect answers.

That online version seems to be corrupted with font character settings.

So I attached it here.
