serial communication time

[skimask]

only 0.4 ms or less to send the data from one pic

I think it is sufficient to transmit that data every 0.1 sec.

9600 baud = 9600 bits per second
1 second / 9600 = .1046 ms per bit
1 byte = 8 bits + start bit + stop bit = 10.5 bits
10.5 x .1046 = 1.0983ms per single data byte = 910.498 bytes per second MAX

The math doesn't work...
