1.5 stop bit?

Started by manuelito01 November 29, 2005
Is it impossible to use 1.5 stop bit for the Com3?

The BX System Library says that Com3 always uses 1 stop bit.

Thanks!

I suspect that the documentation is correct. There is no means to
specify an alternate stop bit configuration.

But the stop period can be lengthened by sending one byte at a time with
a delay to consume the additional stop period. Stop state and idle are
identical. Tom

Assuming that the channel is configured for 8 data bits (or 7 bits
with parity), you'd probably have to put a byte in the queue and then
delay for 10.5 bit times to allow for the byte to be sent. 11 bit
times would get you two stop bits.
