String manipulation---mixed case
Hello,
Does anyone know of a "slick" way to get R to convert a string which is all upper case to a string where the first letter in each word is upper case and all others are lower case?
I suspect the solution is to begin by parsing the string, convert the appropriate letters to upper and lower case using "toupper" and "tolower", and then to paste the pieces back

Lovely, the ServiceBindings are on a handle that resembles the NIC
while the Pxebc is IP-type specific.? Looks like we should try to do a
ServiceBinding based on Pxebc but fall back to MAC-based searching,
saving all 3 handles, the image handle, Pxebc handle, and ServiceBinding handle.?
Presumably the UDP and TCP handles _should_ be the same...

None of Dell OptiPlex 990 (firmware A19), 9010 (firmware A22), nor 9020

We can, and do, suspend a TFTP transfer simply by delaying the ACK packet as necessary.

The only solution for these is to use our own stack (likely full
TCP/IP like lwIP) and connect to the Net GUID (EFI_SIMPLE_NETWORK_PROTOCOL).?
Does the handle for Pxebc contain a Net??

Jeff,
Patrick: Could you try my code from my github repo branch
efi-multinic?? It's derived from
Patrick's code and I finally see good
responses with a VMware VM's e1000e NIC

it until
now).

Not as much as you
may think.? We already have lwIP implemented into lpxelinux.0.? It's more a matter of using more glue.

Pseudo code:? Using the most recently used handle (the one holding
Pxebc by default), attempt to create a service binding.? If unsuccessful,
hunt for a handle that provides the target service
binding and matches the MAC address.
Best case, it's 1 binding attempt.? Worst case it's about N+1.

I looked into this for iPXE. From memory, it wasn't easily possible:
