Feature request: Local Echo

[sk-jame]

Hello, I think that very important feature is missing - local echo. I don't think it should be explained, it is well known interface. So just wanna mention that it would be great to have it here.

[lefebvresam]

I have the same question

@sk-jame @lefebvresam
Please see my pull request, I've just added this feature: #42

[lefebvresam]

When it's available in the installer?

[salvathor79]

@lefebvresam I've uploaded a new version here
v0.9.0

[lefebvresam]

What also should be a nice to have is that you can add an arbitrary sequence when pressing enter. Because some command interpreters expect that you end a command sentence with for instance 0xFF0xFF0xFF.

@lefebvresam
v0.9.1
In this version you can specify a custom string, the string is sent as-is. So no escape character or 0x... format value.

[lefebvresam]

Can you escape them, or use hex values? I want to send 0xFF0xFF0xFF for each string termination.

[salvathor79]

v0.9.2

@lefebvresam now it's possible to specify a custom sequence of bytes to be sent on carriage return

[lefebvresam]

But how do you enter 0xFF0xFF0xFF? As ÿÿÿ?

[salvathor79]

In the new version (v0.9.2) you can simply add the option --tx:bytes="0xFF0xFF0xFF" or --tx:bytes="FFFFFF" or --tx:bytes="FF FF FF" or --tx:bytes="0xFF 0xFF 0xFF" as you prefer.

note: --tx is the short form of --tx_newline option

[lefebvresam]

I use this which is working:

ss -com:COM4 -echo:ON -tx:bytes="FFFFFF" -encoding:RAW -baud:120000

But with the sniffer I see that every character is sent immedately after entering it.
When you have one char wrong you need te retype the whole line.
There is also a wait time between characters in my application before getting a timeout.
Should it be possible to send the whole line + termination only after pressing enter?
In that case it will be possible to edit the line before sending long strings.
Then it's more like a real terminal.

Thanks in advance.

@lefebvresam what you are asking is technical feasible, but this apparently simple modification is against the nature of Simply Serial that is a TERMINAL CONSOLE. In all terminal console programs like Simply Serial (i.e. Teraterm or Putty) each character is transmitted immediatelly, what you are asking is more a "serial tool" like Realterm or YAT.

If you want to correct keyboard mistakes, you can implement it in your application: simply upon receiving the char '\b', that is the backspace characters in C, you should remove the last char received before '\b' from the received string. Obviously this is only feasibile if you don't use any command that can contains the '\b' char :-)

There are a lot more that you can do with escape sequence with a VT100 ANSI terminal like windows terminal and SimplySerial https://en.wikipedia.org/wiki/ANSI_escape_code
