You are going to need a null cable to get that working , the 1900's were different than all other cisco switches as far as connecting into them . Or you can go to radio shack and get a null adaptor to fit your serial adaptor with a straight thru cable. Also if you have internet access download Tera Term for your terminal emulator , you'll have a lot less problems than trying to get hyperterm working correctly and it's also a real good telnet client .

I thought, most 1900s did have a RJ45 port on it, unless yours is a very old model. What kind of switch is it. There should be sticker on the back or side, 1912, 1924 ?

Please see the pinouts for the null modem cable. You can make at on your own.
