I often preach for Fossil serial driver.  Fossil is a standard that handles serial ports on MS-DOS.  The best implementation of Fossil I know is X00 (... that's how it has been named! ...).  X00 is a VERY stable serial port driver that can
be loaded as a .SYS (device) or .EXE (resident).  It can support up to 8 com ports, with buffer size you specify, supports FIFO chips, and much, much more features...   X00 can be found on WUARCHIVE anonymous FTP.  Latest version of X00 is
actually X00v124.ZIP

By the way, X00 also has a break-out box for debugging.
