OpenMSXConTroL Utility and script
'OpenMSXConTroL' is an utility to send control commands to openMSX from within the emulated msx.
Original idea by 'immetoo' implemented with help from 'm9710797'
(see https://github.com/openMSX/openMSX/issues/1133)
## Usage
Pass the script on the openMSX command line:
openmsx -script <path-to>/omsxctl.tcl
And then in MSX-DOS execute something like:
omsxctl set throttle off
...
omsxctl exit
## build
Copy Makelocal.mk.tpl to Makelocal.mk and setup your lib paths and type;
```
make help
```

; MSX-DOS utility to execute openMSX commands from within the MSX.
;
; This can be used to e.g. integrate a MSX program in a build chain
; on the host computer.
;
; For example start openMSX from the command line like this:
; openmsx -script omsxctl.tcl -diska my_directory
;
; And inside my_directory/ put the a AUTOEXEC.BAT with content:
; omsxctl after time 100 "exit 1"
; my_tool my_data.in my_data.out
; omsxctl exit 0

# omsxctl -- execute openMSX commands from within an MSX program
#
# Typically used in combination with the MSX-DOS 'omsxctl.com' utility.
#
# But can also be used from any other MSX program with a code snippet like
# this:
# ld hl,command ; pointer to the to be executed command
# ld de,result ; the result of the command is written here
# ld bc,resultSize ; size of the result buffer (set to 0 if result is not needed)
# out (#2d),a ; the value of A doesn't matter
# jp c,error ; carry-flag set if there was an error executing the command
# ; BC is set to the actual length of the result string,
# ; or set to 0xffff when the result buffer was too small,
# ; in that case the result is still written to [DE] but truncated.
#
# Limitations:
# Strings containing characters >=128 are not handled well:
# - For passing the command string from the MSX to openMSX this could be
# fixed (but is it worth it?).
# - For passing the result from openMSX to the MSX I currently don't see a
# solution that handles both arbitrary utf-8 strings and binary data (e.g.
# created via the 'binary format' Tcl command). The current implementation
# chooses to handle binary data (and of course pure ASCII strings work fine
# as well).
proc trigger_omsxctl {} {
# Read the command string from memory.
set hl [reg HL]
set cmd ""
while 1 {
set c [peek $hl]
incr hl
if {$c == 0} break
append cmd [binary format c $c]
}
# Execute the command.
set err [catch [list uplevel #0 $cmd] result]
# Write the error status to the carry flag.
reg F [expr {([reg F] & 0xfe) | $err}]
# Write the result back to memory.
set len [string length $result]
set de [reg DE]
set bc [reg BC]
for {set i 0} {$i < $bc && $i < $len} {incr i} {

poke [expr {$de + $i}] $c
}
# Write the actual result-length to BC.
reg BC [expr {($len <= $bc) ? $len : 0xffff}]
}
# Register callback on write to IO-port 0x2d.
