Well, with your "-serial" setup, you've put the guest serial console on
the telnet port, so there is nothing to switch on the host console here
via the CTRL-a c key combination, i.e. this is the expected behavior.
What exactly were you trying to do here? Access the serial console via
two ways, one time via telnet and one time via the host console? AFAIK
that's not possible.

  Unable to C-a in -nographic if -serial telnet

Status in QEMU:

Bug description:
  qemu-system-i386 (version 2.6.1, running on Linux/x86_64) started

  qemu-system-i386 -m 64M -machine type=pc -rtc
  base=localtime,clock=host -nographic -serial
  telnet:,server,nowait -net nic,model=ne2k_pci -net

  does not accept the escape key (C-a) to perform functions such as
  switching from monitor to console. Verified both in GNU screen and in
  the Linux console.

  If '-serial telnet:,server,nowait' is removed from the
  command line, the escape key is accepted (and Qemu doesn't enter the
  monitor immediately).
