Serial support by DOS is quite poor. It is nothing more than what is offered by the BIOS, which is non-interrupt driven one character at a time. Most serious DOS serial applications use a 3rd party or built-in serial driver. I don't know of any 3rd party sources offhand because I wrote my own. It is not easy, so unless you want to learn more than you ever wanted to know about interrupts in DOS and assembly language, try to find a 3rd party DOS serial driver.
