I appreciate taking time to give the information. What I'm trying to do is to use a 3210 data cable(switch F/Bus) to COM1. But unfortunately I can't find the cable I need(I'm in a rural area). The one that I see at the cellphone store the data cable at one end has RJ45 connector not Female com connector. I need to use it to send sms information(command) to cellphone attached to the pc and register to my database application and to switch a load(ex. motor) from the parallel port. (Just an experiment for school).
