Jtag interface tty may run with effective speed less than 300 baud (on
some systems). So do a simple calculation:
Buffer size (previous message): 512 Byte (less than 10 lines of 60 chars
Character size: assuming 12 bit (less than that required on jtag)
Line speed: 300 baud (just to take a value)
512 * 12 / 300 = 20.48
That is, it takes more than 20 seconds to transmit the buffer contents
... so that 1 second delay doesn't make much difference.
Just to give an example on why it isn't hard to believe.
