Sending contol-z (^z) over serial interface

[Per Magnus L?vold]

Hi,
I am working with a simple Java program which communicates over the
serial port with a GSM modem.
Using Hypertermial, I can send messages and need to press control-z to
process the messages. I have created a PrintStream over the serial
port, but I do not know how to send control-z from the program!

I fin in another Google- thread that control-c equals decimal 3:
But what is then the equivalent of control-z, and how should it be
transmitted? Could I do:
myPrintStream.w rite(4);
if dec 4 would be the equivalent of control-z?

Hope somebody can help me! :-)

Regards, Per Magnus

I think control z is decimal 26

Thank you, I'll try that later today!
But how can you tell?
I thought of the KeyEvent.CONTRO L value, but that doesn't seem to
work. And it seems as if control-c and control-z is represented as one
single character.
I would like to understand this. :-)

Re: Sending contol-z (^z) over serial interface

When you press Ctrl - A in Hyperterminal, an ASCII 1 is sent out the
serial port. When you Hit Ctrl - B, an ASCII 2 is sent. When you Hit
Ctrl - C, an ASCII 3 is sent and so on...
In other words, the position in the alphabet for the letter determines
the character that gets sent.
Since Z is the 26th letter in the alphabet, Ctrl - Z represents an
ASCII 26 therefore you need to transmit an ASCII 26.

Why are you still using such unhandy thing as Hyper Terminal? Recently
I've found an interesting program - Flash Terminal. It is really Hyper
Terminal killer. With Flash Terminal you can chat and exchange files
via modem (including v.90, ISDN, ADSL, GPRS) and null-modem
simultaneously without Internet! You can exchange up to 255 files at
once with unlimited transfer resuming after connection break. Program
includes large amount of nice avatars.
