PKT
Type: Command
Description: Packet Command: Used to send command “packets” (and receive requested data) to a Kermit
server.
To send calculator objects, use SEND.
PKT allows additional commands to be sent to a Kermit server.
The packet data, packet type, and the response to the packet transmission are all in string form.
PKT first does an I (initialization) packet exchange with the Kermit server, then sends the server a
packet constructed from the data and packet-type arguments supplied to PKT. The response to
PKT will be either an acknowledging string (possibly blank) or an error packet (see KERRM).
For the type argument, only the first letter is significant.
