elimination of intercharacter gap in RS232 stream?

Writing an Embbeded Linux app for a PC104/Versalogic board. Linux 2.6.14.17.

Using write() to transmit data packets to another PC104 board. If I write()
30 bytes, sometimes there is a 2-5mS gap in the middle of the
transmission, usually at about byte 15-20, but sometimes at byte 29--as seen
on a scope. Tried using low latency setting when
opening the port--but this made no difference. This is causing difficulties
for the receiving end-- and we have yet to add two more serial ports to the
application.

Any ideas on how to force continous transmission of the data?


Thanks,

Bo
