{ The following is the INTERFACE section of FCOMM.PAS (FCOMM.TPU).
  It has all of the functions and code you will need, so please don't
  hesitate and give me a ring via the Doorware FidoNet Echomail Conference. }

 FComm - A FOSSIL driven I/O Library for Doors w/lots-of-goodies :)

  - for use with Turbo Pascal 6.0
  - for use with Remote Access v1.0
  - works with RA's *.BBS files, DOOR.SYS and DORINFO?.SYS
  - SysOp "hot-keys" (see documentation or source code)
  - Code supporting Interactive EMSI
  - Emulated "windowed" ANSI & AVATAR graphics
  - Status line on caller
  - Checks for carrier drop, keyhit timeout and time-limit timeout.
  - semi-intelligent code
  - nice programmer who takes suggestions.. (yuck)
  - and FREE.

  - I hope this gets improved by a few programmers out there..  all I ask
    for is to only have one "valid" copy floating around, or chaos will
    definately occur, so please send improvements to:

                   FidoNet NETMAIL @ 1:363/111
               or  Data [phone] (The SCSI Resource BBS)

 A "TRUST-ME" NOTE: THE BEST WAY TO LEARN THIS LIBRARY IS TO KEEP USING IT
                    UNTIL IT WORKS.  THAT SOUNDS BACKWARDS, BUT IT IS THE
                    BEST WAY TO LEARN OTHER PEOPLE'S WORK...
