This software engineering firm creates shared COM-port, Serial-port, and modem solutions for computer architecture. This includes Legacy hardware interface compatibility as well. (Legacy systems are obsolete hardware and software that have not been replaced due to its ease of use and implementation or cost constraints associated with upgrading.) PC Micro's software-related solutions work to automatically redirect or reply with electronic communications such as auto-response e-mails to even more complicated services such as network data packet redirections across remote servers.
