Opening a COM port

I'm having problems opening a communications port. What is a good
general OPEN statement that I can test it with?
The following OPEN statement is very general and will be accepted by most
configurations:
OPEN "COM1: 300,N,8,1,BIN,CD0,CS0,DS0,OP0,RS,TB2048,RB2048" AS #1
For specific information on syntax, see ◄OPEN COM►.
