I'm trying to replace backslashes (from this polyline) with double backslashes.
My Script:
...ANSWER
Answered 2021-May-07 at 20:54The basic problem is that there are no backslashes in your string. Your source code has backslashes, but they are all escape signals. If you want to retain the backslashes in "WYSIWYG" style, use raw

My .txt file I have created before running the code looks like the following:
...ANSWER
Answered 2021-Apr-29 at 11:50You are reading 2 characters for every one you print. The first character was read by "buck=fgetc(filepointer)" as an argument in the while statement. The second character was read by "printf("%c",fgetc(filepointer));".
So essentially your program first reads a character from the file and stores it in "buck", then reading another character and printing it out, resulting in the output missing characters.

QUESTION
Background:
I have an old Seagate BlackArmor NAS 110 that I'm trying to install Debian on by following the instructions here: https://github.com/hn/seagate-blackarmor-nas.
I have a couple of USB to TTL serial adapters (one FTDI chipset and the other Prolific) that I've tried and have run into the same issue with both. I have made the connection to the serial port on the board of the NAS using a multimeter to make sure I've gotten the pinout correct.
Problem:
I'm not able to stop the autoboot process by pressing keys and any point during the boot process. The device also does not seem to respond to any keystrokes although they are echoed back.
What I've Tried So Far:
- Using USB to TTL serial adapters with two different chipsets
- Using the adapters on two different computers (MacBook Pro and a ThinkPad)
- Using different operating systems (MacOS, Windows 10, Ubuntu 20.04)
- Using different terminal programs (Screen, Minicom, Putty)
- Turned off hardware and software flow control
- Tested output of adapters by shorting RX and TX pins and seeing keystrokes echoed back
- Commands seem to be sent to device as when I type I see my commands echoed back (not sure if this is supposed to happen)
I've been at this for a few days and can't figure it out. I've also recorded my screen while experiencing the issue: https://streamable.com/xl43br. Can anyone see where I'm going wrong?
Terminal output while experiencing the problem:
...ANSWER
Answered 2021-Apr-22 at 15:51So it turns out there is a short somewhere between the RX pin and the +3.3V pin which is not allowing me to send anything to the board. Thank you to those who have commented.
