Re: COM port not available for Modem dial-up connection error

Tech-Archive recommends: Fix windows errors by optimizing your registry

Are you using COM1 as debug port? You may have to disable this in your
BSP (location depends on the BSP, usually the file is called debug.c or
..cpp and can be found in the oal).

Good luck,

hi all,


I'm trying to connnect vby seiral comunication a MC35 Siemens GPRS modem to
my Windows ce device (smdk2443).
I set configuration on Networking and dial-up connection by when I try to
run connection wince reports an error:

Port not available: maybe another program is using the port

I have 2 serial ports
COM1 -> only UART0 (where I'm trying to connect modem)
COM2 -> UART1/2/3

Reading 2443 documentation I've found something about Auto Flow Control:

"If users wants to connect a UART Modem, disable auto flow control bit in
UMCONn register and control the signal of nRTS by software."

I'm not sure abuot how doing it cause I dont know where is UMCON register.
Can anyone help me? Anyway coudl it be the reason I'm not getting my
connection?


thanks in advance!!
