DM-Link is a serial port file copy utility. It is a serial port file copy utility. DM-Link requires no special setup/ installation or DLLs, which makes it unobtrusive on your system unlike so many other file copy utlities.

Installation: None, just execute the program

Note:
Before you begin to send files, the receiving computer must be put in Receive Mode. Also, choosing Action->Abort (Esc) from either mode aborts that mode.

1. Receive Mode(on the receiving computer)
* Go to Setup->CommSetup (Control C) to get to the serial port information dialog box. In this dialog box you will be able to set your port, port speed and number of contiguous CRC retries.
* The last setting is only utilized in send mode. Next go to Setup->Receive Folder (Control F) to dedicate a folder on the system to received files.
* Finally choose Action->Receive (Control R) to put DM-Link in receive mode, allowing it to wait for files from the sending computer.

2. Send Mode(on the sending computer
* Go to Setup->CommSetup (Control C) just as we did in Receive Mode. The CRC retry is used to try to get DM-Link to send files even under bad transmission conditions, such as a semi-faulty cable or electrical interference (leave default).
* Finally, go to Action->Send (Control S) to choose a file(s) to send.

Requirements:
* DM-Link simply requires a standard "null" modem cable
* A free serial port D-shell connector on the back of the receiving and sending computers
