Yes, 5-6feet is not so long. A lot depends on the transfer speed you use. If you just wait everything to settle up or get stable, you can use very long cables. Don't forget the earth wire/wires. With high speed and long cables you get transmission lines.

I just sent myself a SMS with Putty. Ctrl-Z in the putty window worked.

I have to try that.
I got putty running and it looks nice.

Yes, I guess I have to. I tried Realterm. It works but it messes up its display.
5  Using Arduino / Project Guidance / How to put a CTRL-z character to the serial monitor send-window? on: July 18, 2014, 05:51:41 pm
I have a GSM modem and I had to test some AT-commands. When I tried to send a SMS, I noticed that I can't send a CTRL-Z to finish it.
6  Using Arduino / Installation & Troubleshooting / Re: Timeout problem : Mega 2560 and Windows on: July 10, 2014, 03:51:00 am
I get timeout messages if I have the board using the serial port at the same I try to upload the sketch.
7  Using Arduino / Installation & Troubleshooting / Arduino 1.5.7 BETA editor freezes when full height on: July 10, 2014, 02:29:14 am
It is not possible write anything to the editor window when I increase IDE height to full screen. The Windows size buttons and menus work and it is possible to end it. If I return the IDE to previous size, it starts to work again. It works at full screen size.

I have installed it into a folder called C:\Program Files\Arduino156, perhaps the IDE protests the wrong version. And it does not help to reinstall the SW.

I have Win 7.

Even if the GSM shield uses SoftwareSerial (it does, but it's a bastardization of the original) that doesn't explain why you are trying to create another instance (of a different class) of a software serial implementation on a device with 4 hardware serial ports. Surely you are not trying to read from 6 serial devices at once.
"The World Is Not Enough" but I used the Software serial because that was what the examples said. Using arduino libraries and examples is usually the easiest way and what I can see, the GSM libraries do not understand extra HW serial ports..

I just downloaded IDE Arduino IDE 156

Hi

Yes, I have v.105-R2 too
10  Using Arduino / Programming Questions / Re: The Software serial multple serial test example does not compile on: July 01, 2014, 05:20:44 pm
I got hardware serial port working. But if use them I must control the modem myself without GSM libraries.
11  Using Arduino / Programming Questions / Re: The Software serial multple serial test example does not compile on: July 01, 2014, 04:07:14 pm
This is a bit confusing.  I thought that the software serial library uses interrupts with RX. And so is new or at least good to use.
This is from GSM modem's reference page.
"It relies on the Software Serial library for communication between the moden and Arduino. "
12  Using Arduino / Programming Questions / Re: The Software serial multple serial test example does not compile on: July 01, 2014, 03:39:42 pm
I see. I thought that the Software serial is what is used with GSM library.
13  Using Arduino / Programming Questions / The Software serial multple serial test example does not compile on: July 01, 2014, 01:26:02 pm
I tried compile the "Software serial multple serial test " example code for Mega 2560. But got an error:
c:/program files/arduino-1.0.5-r2/hardware/tools/avr/bin/../lib/gcc/avr/4.3.2/../../../../avr/lib/avr6/crtm2560.o: In function `__vector_default':
(.vectors+0xdc): relocation truncated to fit: R_AVR_13_PCREL against symbol `__vector_55' defined in .text.__vector_55 section in core.a(HardwareSerial.cpp.o)

The code is unmodified and from examples in IDE. I list it here all the same.
/*
  Software serial multple serial test
 
 Receives from the hardware serial, sends to software serial.
 Receives from software serial, sends to hardware serial.
 
 The circuit:
 * RX is digital pin 10 (connect to TX of other device)
 * TX is digital pin 11 (connect to RX of other device)
 
 Note:
 Not all pins on the Mega and Mega 2560 support change interrupts,
 so only the following can be used for RX:
 10, 11, 12, 13, 50, 51, 52, 53, 62, 63, 64, 65, 66, 67, 68, 69
 
 Not all pins on the Leonardo support change interrupts,
 so only the following can be used for RX:
 8, 9, 10, 11, 14 (MISO), 15 (SCK), 16 (MOSI).

14  Products / Arduino GSM Shield / What are the RX/TX pins the GSM library uses in the Mega2560 on: May 30, 2014, 04:27:17 pm
This is a silly question but I have problems with a GSM shield. It's RX and TX are clearly marked but software defines those in the Mega. I will cross TX and RX of course. That is, RX goes to the TX and vice versa. Arduino's documentation is meant to be easy but it confuses me when there is no mention of TX and RX.

So, when I use GSM library, what is RX on the Mega2560 and what is TX.

If you looking for an IC, which lowers 12V to 3.3V, these can help. 919-R-783.3-1.0 This is a Mouser part number but there many others and from other vendors too.
