Pf escape sequence

Description
The \pf escape sequence causes the PF action to be invoked, with the one or two characters after \pf as a parameter.

Examples
Send a PF1 AID to the host, then type  and send an ENTER AID. String("\pf1foo\n") Send a PF21 AID to the host, then type. String("\pf21foo") Send a PF2 AID to the host, then type. Note the use of a leading zero to prevent the second 2 from being interpreted as part of the escape sequence. String("\pf0223skidoo")
