BSII not compactible with BSIISX??

Hi all stampers,

I have a problem in reading the serial data from the computer COM port by using
the BSIISX!..
The serial data output from COM port was then input to the BSIISX pin P01 by
using the following program, it works very well and all the data were captured
when I using BSII but the wrong data were captured when I using BSIISX
instead!!!

''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
INPUT 1
Speed var byte(9)

get_signal:
SERIN 1, 16468, [noparse][[/noparse]str Speed\8]
DEBUG ? Speed(0)
DEBUG ? Speed(1)
DEBUG ? Speed(2)
DEBUG ? Speed(3)
DEBUG ? Speed(4)
DEBUG ? Speed(5)
DEBUG ? Speed(6)
DEBUG ? Speed(7)
DEBUG ? Speed(8),cr
goto get_signal

''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''

It is just a simple program, can anyone tell me why it not works on BSIISX but
work precisely in BSII??? What is wrong in the above program!!.


Thanks in advance,

Louie Ko

    Baud modes and data rates numbers(16468 for example), not apply same way
    for both BS2 and BS2SX. Timing are different.
    Check BS2SX manual:
    Table 1.6
    http://64.27.84.239/downloads/Documentation/Basic%20Stamps/BASIC%20Stamp%202SX%2\

    The BS2SX has a different baud rate map than the BS2. That might be your
    problem.
