I am having a problem with any command I sent to the LK204-25 that has more than just the CMD_PREFIX CMD format. For example the Set Cursor Position command.

In VB, if I send at 19200 to COM1...

MyComm.Output Chr(254)
MyComm.Output Chr(71)
MyComm.Output Hex(dspColumn)
MyComm.Output Hex(dspLine)

Regardless of the dspColumn and dspLine values, the cursor always positions itself at 1:1

I have tried to send the dspColumn/dspLine as Chr() with the same result. The dspColumn/dspLine values are passed to the function as integers.

Thank you.

Use This :

MyComm.Output Chr$(dspColumn)
MyComm.Output Chr$(dspLine)

You can use Byte instead of integer,all values are less than 256

For some reason the addtion of the $ on Chr worked. In debug it seems to produce the same character but I guess in the black box of VB the $ makes a difference. Thank you very much.

Just to be clear....

Use Chr$() instead of Chr() when sending commands via VB.

When sending commands to the MO (LK204-25) should I send them one at a time or can I send them as one command? e.g.

In VB,

MyComm.Output Chr$(254)
MyComm.Output Chr$(71)
MyComm.Output Chr$(dspColumn)
MyComm.Output Chr$(dspLine)

-or-

MyComm.Output Chr$(254) & Chr$(71) & Chr$(dspColumn) & Chr$(dspLine)

Hello...

You should be able to send it as one command...
