port in use ?'s
 

EDIT: please replace the word port with "address" sorry

Ok, i finally got my modem working but there is a few issues that i dont understand......In my attempts i installed this http://www.usrobotics.com/support/pr...asp?prod=5610a, the program on bottom...I guess that automatically tries to install it to ttyS3.....upon booting it would say this
"cannot use port, already in use"
"/dev/ttys3 no file or directory"

Ok, so that wasnt working finally used set serial to set it up to ttys1, got online and everything was fine....So i figured that that program isnt doing anything so i just removed it. Then rebooted a little while later and when i tried to use the setserial command again (i understand that i have to do every reboot or find out how to set it up so does automatically on boot), but it said that ttyS3 was in use???? So i installed that program from the USR website and then it would allow me to assign to ttyS3, so my question is, what does that program do?? Obviously the port isnt in use...Also i fould out how to make a ttyS3 and 4 by doing this

mknod -m 666 /dev/ttyS* c 4 64

I made a 3 and 4, then tried to set the modem top either one of those and it said port was in use...so does that program enter a command to scan the ports or something?? Im pretty confused, thanks in advance for any help

BTW: i just noticed that when i made the ttyS3 and 4 i used the wrong number for the minor....should i just delete and remake??? -thanks

Ok, reformatted and reinstalled to make sure i didnt mess anything up or that program, setup ttyS4, linked it to /dev/modem and bam it worked.....My only question now is why wasnt ttyS2 and 3 installed??? -thanks
