>i woul like to get and to send information by the port com 1, how can i do ?

Have a look in  the V2TK diretory for serial comms libraries. 

If you want to do it yourself then you WILL need to look a the specs
for a number of UARTS as documented in the various comms libs in order
to take care of the missing / additional registers for the varius
uarts.

Watch the speed you are using and if you are polling or intterupt
driven RX/TX as these can make a big difference.

Good luck. If you get stuck then goto www.delorie.com and search the
past newgroup archive for info.
