null modem cable compared with serial cable ?
how can you tell the difference between a null modem cable and a
serial cable? i've heard that a null modem cable is for connecting 2 computers together. So I guess a serial cable is just for connecting a computer to a device. ? Is it like a straight through vs a crossover ? |

Typically between a DTE (like a PC) and a DCD (modem). A cross-cable allows you to make a connection between two similar devices (like 2 PCs). It does that by connecting Sender to Receiver pins and vise versa. Details: www.hardwarebook.info There, you can also see that a straight cable is always the same cable while a crossover may come in many forms and shapes. Some crossed cables may not work in a given situation! -- Kind regards, Gerard Bok |
