Summary: serial via telnet looses characters in transit

Initial Comment:
I noted that when typing a little bit fast characters get lost. For some while I didn't gave it a though until lately I reset a guest system - in this process I send a pretty larget file via serial (as the guest has no IP configured). The expect script was not even able to login, notably it always stayd at the login prompt, which reapred like:

login:

login:

login:

because in the 'send -- "root\r"' the first 4 characters got lost.

I know slow down the input with 


set send_slow {1 .05}
proc send {ignore arg} {
       exp_send -s -- $arg
}

regards
Philipp
