How to use zModem in android

[Vikas KM]

Hi All,

I am trying to use zModem in Android to transfer files over serial cable.

Go the precompiled libraries for the board from here .. https://github.com/tigerking/zmodem-android

After booting the board

Since i have the adb working on this board.. i ran the 

Following various commands from shell

For receiving

lrz

lrz -vv -b

lrz -vv -b > /dev/ttyO0 < /dev/ttyO0

For Sending

lsz -vv -b init.rc

lsz -vv -b init.rc > /dev/ttyO0 < /dev/ttyO0

and through minicom selected the zmodem protocol to send/receive the files..

But i always get timeout.

What am i doing wrong??

Has anyone tested zModem working on Android?

Sounds like an interesting project, but not on topic for the ndk
group.

You'll need to verify the serial drivers and hardware and device
files. Writing a program to send endless data to one might not be a
bad start; also consider you may need to play with line settings -
this would be much more in the realm of ordinary linux serial issues.
The only real android question is if there is hardware, driver, and
permission support - the answer in terms of the ndk platforms released
to date being "assume there isn't".

Why not just use adb push/pull?
