Now, question #1, what program are you running that needs com2? #2 - Is this software you are writing for a PC or MAC #3 - If not software by someone else, what language are you writing the program with? #4 - DOS or Windows If you just need to set a com port to receive data to use as printer output or redirecting data from pc to serial out, use the MODE command in DOS for example MODE COM2;9600,N,8,1 sets the com2 to the indicated speed and bit mode. MODE LPT1:=COM2: will send printer output to com2 Using a program written by someone else, READ THE BOOK. You will have to look to see what keystrokes they use to setup the comport for use with their program. For ex. in PCPLUS, a popular terminal program, you use Alt-P to select port setup, F1 for com1 F2 for com2 - 2 for 1200 baud, 3 for 2400 baud, etc. In essence, Not enough information was conveyed in your post to give a usable, accurate response.
