Hi

I want to connect the two linux RedHat 9 machines through null
modem cable. I did it correctly using ppp. Now the two mechines are
able to ping and I am able to telnet also. But the problem is I am not
able to transmit the messages.
ie.. When I am giving the command as cat </dev/ttyS1 ( where I
used com2 for serial connection), error message displaying like
'Resource temporarily unavailable '

I checked all the configurations. All PPP configurations are OK..
and the ifconfig also it is displaying correctly.

Pls help me where is the error? I am not able to do
cat < /dev/ttyS1.

Thanks in advance
Praveen
