My embedded system uses a serial port for configuration and loggin operations. Then, software running on a notebook computer communicate with this embedded system to process configuration and logging data. Th software running on notebook computer implements a DOS-based serial drive not Windows-based serial driver. This serial driver is pretty old.
Most newer notebook computers no longer come with serial port. Instead USB and PCMCIA ports are available. I have contacted many vendors tha offer USB-to-serial port adapters and all of them tell me that thes devices only work with Windows-based serial drivers. I also contacte vendors that make PCMCIA-to-serial port adapters and I get mixe responses. A couple have told me that their PCMCIA adapters will wor with DOS-based serial drivers.
Anyone have any experience with PCMCIA-to-serial port adapters?
