| | | Hi Can anyone tell me why a call to lnp_addressing_write(...) might block? My environment seems okay. I have some simple clients written that have no difficulty in communicating wth the RCX, but I have one client ( a lot more complex) which seems to (...)

| | | | HELP! I'll ellaborate a little on the details of my previous posting: My code (removing some CORBA detail) looks like this: I have a class "nanOrbDemo_i" which has the following constructor: inline nanOrbDemo_i(){ if ( lnp_init(0,0,0,0,0) ){ cout << (...)

How about: result = lnp_addressing_write...estbuffer, testlen ,testaddress, testport); Bye, Paolo. --- Maier's Law: If the facts do not conform to (...)

| | | | (...) From the statement "data is received by the RCX" I assume you have this problem on the host system. What OS are you using? Also, how does your lnp_logical_write() routine look like? Eddie C. Dost ecd@skynet.be (24 years ago, 27-Aug-00, to lugnet.robotics.rcx.legos)

| | | | (...) Yes, the problem is on the host PC (running Red Hat 6.2). What I cant figure out is how identical code works fine if I instantiate the wrapper class in a simple demo app, but once I try calling it form within my CORBA server, it blocks on (...)

No, I meant lnp_logical_write, which is called from lnp_addressing_write. lnp_logical_write is not within the file lnp.c, which I guess you link into your app. This function is supposed to actually write to the serial device communicating with (...)

Is there a way in which I can call lnp_logical_write directly to test (...) (24 years ago, 28-Aug-00, to lugnet.robotics.rcx.legos)
