Please if someone Knows how I can open com1 and sent any kind of data to open a cash drawer. The drawer accept any type of data and performs its functions. Thank in advanced.

You can't do it directly with FoxPro. Fox can't open ports. You need a third-party interface. Here is a site you can check:

try this:

You must print before running this procedure (if your drawer is attached to a serial printer)


procedure cash

port="COM1"

handle=FOPEN(port,11)
=FWRITE(handle,CHR(27)+"@&quot
=FCLOSE(handle)

handle=FOPEN(port,11)
=FWRITE(handle,CHR(27)+"@&quot
=FWRITE(handle,CHR(27)+CHR(112)+CHR(0)+CHR(100)+CHR(250))

=FCLOSE(handle)

Gigatech,
I hope you know that this will likely NOT work on NT / 2000 / XP, and depending on configuration settings and other applications, may not work under 95 / 98 / SE / ME.

Writing directly to COM ports directly with low-level IO only works consistent when running FPD on DOS (not in Windows). Even the FPW help file states "Ports cannot be opened with low-level file functions in FoxPro for Windows and FoxPro for Macintosh."

I work with POS application under FPW26 on Windows 95/98/ME and I open cash drawers, write in Customer displays and print "in line" without problems.

You are right, it does not work on NT/2000/XP

I set the com port up to be a printer port and then send something to it. Like this...
************************
! mode com1 96,n,8,1 * Run once
! mode lpt3 = com1 *
************************
then.....
***************************
save sys(6) to MPRINTERWAS* To open the drawer
set printer to lpt3 *
??? "X" *
set printer to MPRINTERWAS*
***************************
You could probably just set the com port up with...
! mode com1 96,n,8,1 && run once
set printer to com1
??? "X"
