Hello Harald and Lukas,
In my opinion regarding non-standard speed, PL2303 based cable should
never succeed to load code into calypso ram...
The wiki says that for some branch and/or firmwares it works, I don't
understand how it can happen.
btw with my pl2303 cable what branch / firmware do i have to use for
loading a GSM layer1 into my C123... with succeed?
Ps. I bought a RS232 / Jack adaptator. I wait for it... (I already have
a FTDI RS232 / USB cable) - If i have a little time I can braze a jack
on the RS232 as explained on the wiki
Sorry for my late answer and thank you both for your help.
I didn't had time to work on my problem :(
(right now I have trouble with my soft raid 10 in dual boot who drives
me crazy!)

have/had problems handling baudrates
above 115200, there was a recent update into the kernel tree, but I've never
tested it.
the problem is not "[standard] baud rates above 115200" but
it is
"non-standard baud-rates at all". Normal USARTs have baud-rate
generators that can only generate baud-rates "input_clock / divider"
where divider is either an integer, or even more: limited to a power of 2
The calypso cannot do any standard baud-rates above 115200. That's why
you need a USART with more flexible baud rate generator. The most
commonly known one to do this is the FTDI series of USB-serial
converters.
