UNIX for Dummies Questions & Answers

Hi,

Now I am programming to communicate with some network printer through TCP Socket program.By sending command "\033E 1\r" to printer,causes, check the port for error normally.

In my case i used following code

Code:

   bytesSent = send( sockfd, "\033E 1\r",sizeof("\033E 1\r"), 0);
   bytesRecv = recv( sockfd,recvbuf, 1024, 0 );

Here command goes to printer proper manner.But when i try to receive the recv gets blocking can not able to read anything its hanging there.

Then i used Non Blocking Socket with select() method in this case i am getting "Resource temporarily unavailable".

Please help me to figure out this error

Thanks in Advance
Regards
Siva

You need to escape the\ character "\033E 1\r" : "\\033E 1\\r"

Are your sure it is \r ? not /r? /r == carriage return
