please reccomend some DNC software with following protocol

Hi group
I have a cnc milling machine named TRIAC. I need to send program
block by block to this machine via some dnc software installed on a
PC via RS232 port. This machine has some special requirement for its
protocol. It uses three wires Rx Tx and GND for
its RS232 communication.

The protocol of the machine requires an STX character (0x2) before
each block and a CR character after the block. The machine starts
executing the block as soon as the CR character it receives. And The
machine sends the ACK character (0x6) when it finihes executing the
block.

Therefor the DNC software must wait for this ACK character before
sending the next block.

I need some software that can send programs to the machine according
to this above mentioned protocol.

Please reccomend any DNC software that can be configured to run with
this protocol.

Best regards
Asim
