Probe Type Pop-up Menu

When testing AppleTalk devices, you can select from Automatic,  Short Echo packets (8 data bytes), Long Echo packets (580 data bytes), Name-Binding packets, Printer Status packets, LocalTalk RTS-CTS packets (if MacPing is directly connected to the Local Talk network under test), Custom Echo packets, or Random Echo packets.

In Automatic mode, MacPing alternates between sending Short Echo packets and Printer Status packets until the device answers a particular packet type. MacPing then continues to probe with that packet type. 

When testing IP devices, the Probe Type pop-up menu has Short, Medium, and Long ICMP Echo packets (8, 544, and 1,472 bytes respectively), as well as SNMP Request, Custom ICMP Echo packets, and Random ICMP Echo packets.
