Yes.

If you are lucky you received some manual for the motherboard if
these ports are on the motherboard. Otherwise you have to look for
the serial port card and see what kind of chips are on there.
In general manufacturers have used better serial ports over the last
years. Make sure you have at least a 16550 UART !!!
Important: Make sure the port does not share an interrupt with
another device.
Even more important: If you have NT and a 16550 UART read the
following:
Using the Registry Editor (/system32/REGEDT32.exe):
Select the key:
\HKEY_LOCAL_MACHINE\System\CurrentControlSe
t\Services\Serial Make sure you
have the following:
ForceFifoEnable REG_DWORD 1
LogFifo REG_DWORD 1
PermitShare REG_DWORD 0
RxFIFO REG_DWORD 8 or C for a fast
machine TxFIFO
REG_DWORD 10 - for
maximum write throughput If not, change and/or add
values. Exit the registry and reboot the system.
The system event log should now have: a. User
configuration data overriding firmware. b. While
validating that COM1 was really a serial port,
a FIFO was detected. The FIFO will be used.
Make sure that no other setting in serial\parameters\serial0 etc.
override these above settings. Basically the rxfifo and txfifo
settings should match your hardware. But txfifo can be higher to
release resources to rxfifo.
