Look at the files in the Crynwr Collection:
   ftp://ftp.crynwr.com/drivers/pktd11.zip
   ftp://ftp.crynwr.com/drivers/pktd11a.zip
   ftp://ftp.crynwr.com/drivers/pktd11b.zip
   ftp://ftp.crynwr.com/drivers/pktd11c.zip
The last three are ASM source.  In particular, look at the source for 
SLIP8250, which is a Packet Driver that talks over a serial port.  Then look 
at PACKET_D.109 to see what a Packet Driver is and why it is useful.  These 
files are also available for FReq (1:323/107) or download (+1 401 944 8498):

If you get this far, you might also want to pick up the old MIT/CMU DOS 
networking package, for FReq (1:323/107) or download (+1 401 944 8498):
PCIP_ALL.ZIP 2594K  6-06-96  Complete set of PCIP freeware TCP/IP for DOS, 
with
                             source and docs
If you are really serious about teaching yourself this stuff, then I suggest 
that the best approach would be to run Linux.  Since it is a whole Unix-clone 
operating system with full network support and full source code, it allows 
you to see a great deal without making you reinvent the wheel.
