serial expasion boards

[Ricardo Denis]

hello,

i want to add a couple of tnc's to my system but i have run out of serial 
ports. before i run out and buy some multi port board that won't work with 
linux, could someone recommend me one please? PCI or ISA? maybe even an 
alternative solution to serial boards? i only need 2 more ports for 2 
tnc's. thanks for your suggestions.
