You're not the first to have this chicken-and-egg situation with Kermit; the Kermit distributions have C and FORTRAN programs to turn an EXE file into a BOO file, which can go over an ASCII link and be decoded by a smallish BASIC program called MSBPCB.BAS (there are C and Pascal version of this, too).
