Question establishing connection with e-kermit running on LINUX from my operating system
we designed a primitive operating system for learning basics fundamentals and we created process switching, interrupt/polled IO for device drivers like UART and printers. We accomplish this by using our own tools called SPEDE (for downloading compiled elf image from host ubuntu system that have SPEDE specific old c compiler to the target system RAM using UART com1 port). One of my project work is to extend this to write device drivers for IDE and integrate file system say FAT16 and download files from host to target using another UART cable-connection.
url is
github.com/bicepjai/nanos/tree/master/nanos_src

I am in the last part of downloading and used simple e-kermit to download files from host to target, but i am facing problems like data loss in transmission. I have taken out all the extra code and have the code just for downloading files from host to target in
the url is
github.com/bicepjai/nanos/tree/master/download_file_uart

The code have some printf statements, but they are omitted since it takes more time to execute. I have disabled the interrupt driven system and using polled IO for preventing any kind of loss. still i have data loss in transmission and have been trying to get over it for more than a month.

Any suggestions will be much appreciated.

clone(7)						 Miscellaneous Information Manual						  clone(7)

NAME

       clone - opens a major and minor device pair on a STREAMS driver

DESCRIPTION

       The  driver is a "pass through" device driver that allows other drivers to select unique minor device numbers on each In effect, the driver
       passes an open operation through to the other driver.  This mechanism allows for multiple instantiations of a driver, each with a different
       minor number, through a single device file.

       When  the  driver  is opened, it is passed a major and minor device number by the operating system.  The major number is the driver's major
       number (72), and the minor number is the major number of the driver the user wishes to clone (referred to here as the target driver).   The
       driver  calls the open routine of the target driver with the flag which specifies a clone open.	The target driver's open routine allocates
       an unused minor number.	The target driver must use to make a new device number for the newly created device,  and  must  set  to  the  new
       device  number  returned  by The new device number is returned to the open through The open then returns to the user a file descriptor that
       points to the new instantiation of the target driver.

       The driver is an example of a clonable driver.

   Notes
       It is not possible to do multiple opens of a device with the same major and minor number using the driver.  This is because the	driver	is
       only given the major number of the driver to be cloned, and that driver will then select a minor number which has not been opened.

       When  called  with  a  pathname	which  corresponds  to the clonable driver, will return different results than when it is called on a file
       descriptor returned from of the same clonable driver pathname.

RETURN VALUES

       If the driver is given an invalid minor number, or if the driver indicated is not a clonable driver, the fails and is set to [ENXIO].
