# 11. Link port

The link port can be set-up with the Link options item:
Note: no DirectLink support!

## 11.1 Direct File loading

When cable is set to internal, TiEmu uses its direct file loading/saving capability. That is to say, you can 'send' a file from disk to TiEmu and vice-versa (Send file to TiEmu item of popup menu).
The port and calc settings are not used.
The timeout value can be increased/decreased to adjust timeout of direct file loading which is not the timeout of real cables.
Please note that the calculator must be on the HOME screen while using this feature. No need to go into the VAR-LINK menu and set the calculator in receive mode; anyways, it will not work!

## 11.2 Virtual cables

There are 2 virtual cables: VTi & TiEmu.
To connect VTI and TiEmu:
- run VTI; next, run TiEmu
- choose the VTi cable, port #2
- open the VTI menu, go to Enable Cable Link and be sure that Virtual Link is checked.
To connect TiLP2 and TiEmu3:
- run TiEmu; next, run TiLP
- choose the TiEmu cable, port #1 in TiEmu
- choose the TiEmu cable, port #2 in TiLP
To connect TiEmu and TiEmu:
- run 2 instances of TiEmu
- choose the TiEmu cable on both, port #1 and port #2 respectively.
Note : the VTI logger can not be used with TiEmu.

## 11.3 Real cables

At the time being, there are 4 link cables useable with TiEmu: GrayLink, BlackLink, ParallelLink and SilverLink (Win32/Linux only).
A cable is plugged into a port. There are 3/4 ports depending on the cable type:

| BlackLink or GrayLink | ParallelLink | SilverLink
| Windows | Linux | Windows | Linux | Windows
port #1 | COM1 | /dev/ttyS0 | LPT1 | /dev/tipar0 | 1st cable
port #2 | COM2 | /dev/ttyS1 | LPT2 | /dev/tipar1 | 2nd cable
port #3 | COM3 | /dev/ttyS2 | LPT3 | /dev/tipar2 | 3rd cable
port #4 | COM4 | /dev/ttyS3 | N/A | N/A | 4th cable

Note: the TiLP 2 framework does not rely on Linux kernel modules any longer. But, you have to take care of permissions (user/group, rw) on the device node.
