tmgr_write hangs?

[rahulgd]

Hi All,

I am working on a application which interacts with ttymgr of LynxOS. I write to ttymgr using tmgr_write in driver. Return value of tmgr_write shows me that I am able to write properly. But at one point I see that I am not able to write to the driver using function tmgr_write. I am also not able to check return value in this case as driver kind of hangs. But through some debug statement I am sure that tmgr_write call has not gone through at all.
Could any one please let me know what could be going wrong? or if anybody has seen this kind of scenario, pls let me know.

Thanks in advance,
Rahul
