You would have to do some sort of recv()  or read() (Is there a RdLine?) and see if it says "ACK".

I'm working on sending requests via sockets (

status of the machine via a socket write, and an ACK + CR response is a
success. The WrLine() procedure call returns the length of the data
written, but how do I check for ACK + CR? Is it sufficient if the length
written matches the data I tried to write?

TIA
