...uld be surprising after decades worth of expected behavior, or that it for some reason decides that the FD #7 (whoever that is) raised the hand but was then silent (0 bytes read). The next clue is 128 reads, which leads to https://github.com/networkupstools/nut/blob/v2.8.0/clients/upssched.c#L485 `sock_read()` method which indeed does up to `US_MAX_READ==128` attempts to read one byte from a connection (so from the CLI/child counterpart) at a time - so that is who FD#7 gotta be.

Dear R Gurus, for some purpose i have to use a socket connection, where i have to read and write both text and binary data (each binary data package will be preceeded by a header line). When experimenting, i encountered some problems (with R-2.0.1 under different Linuxes (SuSE and Gentoo)). Since the default mode for socket connections is non-blocking, i first tried socketSelect() in order to

FWIW, I wonder if this is a fallout of PR #1274 : https://github.com/networkupstools/nut/pull/1274/files and specifically https://github.com/networkupstools/nut/commit/550064930e369fb3a322c3b28ffff8b4acf53532 which added a `sock_read()` loop continuation effectively if `pconf_char()` returned 0. Just grasping at straws here (since it is a change a couple of months before the release was cut), because if ALL of those 128 reads (skipped above) did return 0, we should not have got to this line.
