[G4] Accessing serial port on G4

[Ernest Vincent Pons-Worley]

I recently bought a PCI card to add a 9 pin serial port on a Power  
Mac G4 (AGP Graphics) dual 450 MHz, 960 MB SDRAM computer.  Does  
anyone here know how to access the serial port from the command  
line?  I'm thinking maybe it's ttys1, but I'm not sure.  (On a PC it  
would be com1).

I'm tying to use ckermit to connect to a 1992-vintage HP 95LX.

Thanks,
Ernest
