Write from PI to com(AIS) port

[rooiedirk]

A friend did ask me if it would be possible to write a plugin for programming the static voyage data in a class A AIS tranceiver from OCPN.
This data can be changed by sending a simple nmea sentence to the AIS.

$--VSD,x.x,x.x,x.x,c--c,hhmmss.ss,xx,xx,x.x,x.x*hh<CR><LF>
1 x.x Type of ship and cargo category, 0 to 255
2 x.x Maximum present static draught, 0 to 25.5 metre
3 x.x Persons on-board, 0 to 8191
4 c--c Destination, 1-20 characters
5 hhmmss.ss Estimated time of arrival at destination (UTC)
6 xx Estimated day of arrival at destination, 00 to 31 (UTC)
7 xx Estimated month of arrival at destination, 00 to 12 (UTC)
8 x.x Navigational status, 0 to 15
9 x.x Regional application flags, 0 to 15

Can I send this message from my (to be written PI) to the AIS or is it blocked by the connection filters?
