| - | I've added a parameter to send an LCP echo to the client to test if the connection is still up. If the connection has abruptly been closed, pppd will know this by not receiving an echo reply, and will exit and relinquish control back to the vmodem.sh script. The only reason the timeout is in there, is because it seems like Trumpet Winsock 3.0 doesn't know how to tell pppd to terminate a PPP session from within a PPP session, and it will just attempt to hang up the call. As a result, pppd daemon will be left running indefinitely. This is obviously not preferred, so LCP echo is added to let pppd know when the link has been cut. If you can think of better ways to accomplish this check, feel free to send tips on how to improve the script. | + | I've added a parameter to send an LCP echo to the client to test if the connection is still up.
