open/Close com ports

New User,Thanks for reading this;
I'm trying to setup a bat file to open com2 4800b 8n2
and send 2 commands to my radio.But Ive forgotten how
to "OPEN" port,or maybe the command "OPEN" is usable
?  Any help appreciated.

mode com2:48,8,n,2,b should be the command you're looking for, I think... Then you can copy a file to the port containing your commands.

Find a full copy of DOS 6.22 and copy the QBASIC*.* and HELP*.* files to your Win9x c:\windows\command directory, and you'll have a nice reference to DOS commands, most of which work the same between DOS 6.22 and DOS 7.
