524 | The connect command is #if 0 because I hadn't thought of an elegant |
525 | way to wait for I/O on two serial_t's simultaneously. Two solutions | |
526 | came to mind: | |
c906108c | 527 | |
c5aa993b JM |
528 | 1) Fork, and have have one fork handle the to user direction, |
529 | and have the other hand the to target direction. This | |
530 | obviously won't cut it for MSDOS. | |
c906108c | 531 | |
c5aa993b JM |
532 | 2) Use something like select. This assumes that stdin and |
533 | the target side can both be waited on via the same | |
534 | mechanism. This may not be true for DOS, if GDB is | |
535 | talking to the target via a TCP socket. | |
