Many laptops and even some desktops no longer come with serial connectors. However, many cell phone and PDA data cables are only available with serial connectors. Adding to the problem are the drivers that come with USB to serial adaptors. Most adapters have different drivers making it nearly impossible to support USB to serial adaptors for PDA Seizure, Cell Seizure, & SIM Card Seizure. We have therefore found one USB to serial adaptor that is supported by all our software and we're offering it to our customers.
