Any 1155 mobo with multiple serial ports? Or must use adapters?

[Zardnok]

My son needs a new computer for his stereo/tint shop bay. They have multiple plotters, sign cutters, and graphics machines that need serial ports. Their current machine is 10 years old and showing its age. Currently they are using some USB to Serial adapters, but he says there are issues with packet loss and communication issues that the cutter/plotter manufacturers are blaming on the USB adapters not communicating both ways. Having the plotter crash and waste their sign stock is getting expensive.

He asked me what I thought and I in turn ask all of you. Is there an 1155 mobo with multiple serial ports? Will we need to try PCI to Serial adapters instead of USB? Would a modern computer with USB to Serial adapters function any better than a 10 year old Dell?

I browsed Newegg and didn't see anything, but I thought the collective wisdom at Anandtech might give me some better idea of where to shop next or an idea of what to shop for. Thanks in advance!!

I once needeed them for my CNC machines
the bi directional is the handshake parameters which has to be set in your software app if you are using serial itself. - like 8 stop bits - all that stuff. If your machine uses g-codes you could use any older cad cam program like mastercam 9 or 8, or any posting program like Gibbs poste haste. Most g-code editing sw has output communication module, for use after finishing program

And the P8P67 has a single white ser port "com1" on bottom of mobo next to case header
Same with my GIGA P45 (COM A)

I vaguely recall also using a parallel (printer) to serial adapter for a while

Heres a 4 banger

Not likely for a modern mobo to have more than one of a legacy port... I'd just go with getting a PCI to serial port adapter. That way, it would at least look like it ran from the mobo.

Digi has several serial port cards http://www.digi.com/products/serialcards/ . There are, however, a lot of settings that could affect the communication (baud rate,stop bits, parity,ready-busy or xon-xoff, etc.) all these settings must match the settings on the device attached to that port.
