You can not serout a combination keystroke.· Combination keystrokes can only be recognized by your PC.· You could send a "Z", and then tell the Stamp to perform the appropriate action when the "Z" is received.

Do you have a Stamp Tester yet?

Kenobe -

I can only presume that this is going to be used to emulate a CTL Z from some other device. Which device would ordinarily be sending it, a PC AT keyboard? What device will be receiving the character string, something attached to an MS-DOS port?

What you produce as a character string will very much depend on what kind of device you're emulating. A VT-100 terminal will produce one set of codes, a PC AT keyboard will produce another, and a Wyse 50 terminal will produce yet onther. See the problem you're faced with.

In almost all case I can think of, you will be sending more than one character to emulate it, and in some case you may be sending up to 4 characters, if both MAKE and BREAK keypresses are required by the receiving device, or the software decoding it.

Regards,

ASCII 26 is control Z or in other words binary 0011010 or two char code 94 ,122
94 being control, followed by 122 the char z.

SEROUT pin,baud,[26]
or
SEROUT pin,baud,[94]
then
SEROUT pin,baud,[122]

Are you sure what you're seeing as CTR isn't actually the ASCII escape character?· I'd suggest you do some more research on modem strings, especially for the modem you have...

A CTRL-Z ascii is CHR(26). That's probably what the modem wants as its 'return to command mode' escape character.

Allan, shouldn't that be CHR$(26)?

Sure, in Visual Basic. In Turbo Pascal, the other is correct.

In PBasic, it would be:

SEROUT 16, I9600, [26]

I am very appreciatetive of all your suggestions and helps,

I tried

serout 8,I9600,[26]

It did not work

However, the CTR Z works fine in the Hyper Terminal.

I am trying to send to the Itegno modem.

Well, somewhere you need to have:

I9600 CON 16384 ' Or, whatever the Inverted, 9600 baud modifier is for your BS2.
