I have a module that is usually bundled with a master module, which we now want to use unbundled. The module uses an RS-485 interface. The problem is, by default, the module runs at 1.25 Megabaud, which is not one of the "standard" speeds that most integrated PC serial ports run at.
For my own uses, I can whip up a relay system using some microcontroller demo boards I have lying around, but we also have a desire to make this usable for people without mad embedded skills.
So, does anybody have experience with, e.g. PCI-to-serial cards that can run this fast? It's fine if we end up with a fast RS-232 card that then goes to an RS-485 converter, although it would also be cool if they actually had a PCI-to-RS485 card that worked standalone.
