How to send ASCII messages to port

[Martin]

Hi, I´m expecting to get some help on this issue. I have a printer which uses
ASCII codes to work (I got them from manufacturer), but I don´t know how to
send these messages to a COM3 port from access (I´m working with Access
2003).

Does anyone of you know how to do that? I was wondering if there´s an API
for that. At least, turn on the lights, please.

Any help on this is greatly appreciated, thanks in advance.

hi Martin,

Hi, I´m expecting to get some help on this issue. I have a printer which uses
ASCII codes to work (I got them from manufacturer), but I don´t know how to
send these messages to a COM3 port from access (I´m working with Access
2003).

E.g.:

Dim command As String
Dim fileHandle As Long

command = Chr(13) ' your ASCII sequence
fileHandle = FreeFile
Open "COM3:" For Output As #fileHandle
Print #fileHandle, command
Close #fileHandle

You could try my LinePrinter class module, which is able to send binary data
to a named printer, using the Windows Print spooler. The printer can either
be connected locally, or on a network.

So long as your printer is configured correctly, the spooler will find it
and do the job.

Get the class module and a sample mdb here:
