This version of KERMIT is written in Digital Research CP/M-86 assembler,
ASM86.  It is designed to support any CP/M-86 system.  So far it supports:

    DEC Rainbow-100
    NEC Advanced Personal Computer (APC)

Features and restrictions:

. Performs all standard KERMIT functions.
. Has commands for file transfer with KERMIT servers.
. Runs up to 9600 baud on all systems tested.
. Can time out.
. Can do 8th-bit prefixing.
. Can exchange files with IBM host.
. Can send BREAK.
. Can do protocol to interrupt a transfer (^X/^Z).
. ^C during file transfer gets back to Kermit-86 command level.
. Can log terminal session. 
. Has TAKE command and KERMIT.INI file.
. Local CP/M functions (ERA, DIR, SET DEFAULT disk) as in KERMIT-80.

. No repeat-count prefixing.
. No 2- or 3-character block checks.

Known Problems:

. SET ESCAPE ^x doesn't work for certain control characters, like ^X.
. SET IBM and SET FLOW should interact appropriately.

CP/M-86 KERMIT is broken up into several source modules:

    86KERCMD.A86	Command parser
    86KERFIL.A86	File handler
    86KERIO.xxx		System Dependent I/O, xxx = RB, APC
    86KERMIT.A86	Main Program
    86KERPRO.A86	Protocol Module
    86KERTRM.A86	Terminal Emulation (v 2.6 and later)
    86KERUTL.A86	Utilities

The main program module, 86KERMIT.A86, contains INCLUDE directives for the
other files.  86KERIO.xxx files exist for each system supported (Rainbow,
APC, ...).  The program may be built on the CP/M-86 system by obtaining
all the source files listed above, storing them on the current disk with the
names indicated, renaming the appropriate 86KERIO.xxx file to 86KERIO.A86,
and then doing:

    ASM86 86KERMIT $PZ  (this takes about 6 minutes on the Rainbow)
    GENCMD 86KERMIT     (takes less than a minute)

and, if desired,

    REN KERMIT.CMD=86KERMIT.CMD
