Syntax:
Set Value:
AT#UDPPORT=<Value>
Get Value: AT#UDPPORT? or AT#VUDP, AT#VALL
#UDPSERV UDP Server
Definition:
If the UDP session is initiated in listen mode, use the IP address filter. This means that the remote must
have a defined UDPSERV IP address.
If the UDP session is initiated in active mode, use the remote IP address.
