db9 & db25 connectors

[Rick46]

I used to work at a place that used dnc to feed there programs to the machines. They had these adapters that plugged into the respective ports and utilized plugging a simple cat5 network cable into the ends of said adapters but the crossover or null modem cable effect was taken care of via these adapters thus preventing having to build your own cable for those not very good with soldering in tight spaces like the pin outs on the back of the connectors. Does anyone know what these are called or who makes them ? thanks in advance.

Zoober do these adapters work with the adapter just on the DB25 machine side of the cable and then utilize the network port on the back of the computer since most if not all newer computers have no serial ports. I found some on newegg but I didn't know If I just need the db25 for the machine and the Ethernet port on the pc or both ends and a serial port add on card for the computer itself. Thanks..

They will make the cables, they are pricey, but their cables work!
