Many communications protocols have been implemented in Forth, from GM's 
MAP in the 1980's through TCP/IP nowadays, as well as many custom, 
application-specific protocols. One relatively early implementation is 
described in this article: 
http://www.complang.tuwien.ac.at/forth/jfar3-2-47.pdf. That application 
is still (as of about a year ago) in use. The actual protocol was 
designed and written from scratch in about a month.

If you are using a hosted Forth (i.e., running under an OS such as 
Windows or *nix), you can presumably use some system functions. A purely 
native Forth, such as in an embedded system, may require more custom 
coding. The commercial systems from FORTH, Inc. and MPE provide various 
protocol layers depending on your needs.

If you're asking whether it's possible to implement this in Forth, the 
answer is yes, it's a straightforward programming task. If you're 
looking for an off-the-shelf or published package that meets your 
specification exactly, you will probably find that you have some 
customizing to do, depending on what code base you're starting from.

Cheers,
Elizabeth
