633 Serial to USB Problems


New member
I bought a 633 serial and to save money i didn't buy any cables with it.

So i took a 9 pin header to a Male DB-9 cable from an old 486 that i had and then hooked that up to a USB232A that i got from a friend. The brand is the same. The usb adapter is recognized but the LCD is not recognized by Crystal Control at all even if i make sure that the COM ports match..

Any ideas would be nice.
