What kind of cable do you use, what terminal or terminal emulator and
what communication settings?
I never have problems with net5501 connected to a serial port on a
FreeBSD laptop or server (either standard sio port or FTDI USB/serial
converter) using a null-modem cable that also crosses modem control
lines:
RxD --\ /-- RxD
X
TxD --/ \-- TxD
CTS --\ /-- CTS
X
RTS --/ \-- RTS
DSR -+ +- DSR
| |
DCD -+\ /+- DCD
X
DTR --/ \-- DTR
(My favorite null-modem cables are the light blue flat telecom cables
and separate teledata RJ-45/DB9 converters that used to come with Cisco
routers but haven't seen them delivered with these routers lately.)

That's probably not trivial to implment as a GPT table normally takes
more space than is available on a MBR device.
With kind regards,
