What are EXTFSK and EXTFSK64?

EXTFSK is an MMTTY plugin that enables FSK keying via a USB-serial adapter and a parallel port. See this page for more information.

EXTFSK uses DLPORTIO for LPT port keying. However, DLPORTIO does not work in the 64-bit Windows environment. EXTFSK64 uses inpout32 instead of DLPORTIO and works on the 32-bit and 64-bit Windows OSes.

LPT setup

Open the MMTTY setup and click on TX tab. Select EXTFSK64 in the drop-down list of PTT&FSK.

Click on OK, then the EXTFSK window should be popping up.

Select LPT1 in the drop-down list of Port. Addr value may vary in accordance with the PC environment.

If you have a parallel port that has a non-standard port address (other than 0x378, 0x3bc, or 0x278), open EXTFSK64.ini and add its address (hex value) after LPTADR=. The following example illustrates how the port address 0x1234 is defined in EXTFSK64.ini

[Window]

Left=1376

[Settings]
Port=COM1
FSK=0
PTT=2
InvFSK=0
InvPTT=0

[DirectAccess]
