Commands to send to the modem to set the record/play format.
One or more command strings can be used. For example,
HKR, LineSetPlayFormat, 1,, "at#vls=0"
HKR, LineSetRecordFormat, 1,, "None"
HKR, LineSetRecordFormat, 2,, "NoResponse"
HKR, HandsetSetRecordFormat, 1,,"at#vsr=7200"
HKR, HandsetSetRecordFormat, 2,,"at#vbs=4"
HKR, HandsetSetPlayFormat, 1,,"at#vsr=7200"
HKR, HandsetSetPlayFormat, 2,,"at#vbs=4"
If the modem is using the serial wave driver, and the baud rate needs to be set, the baud rate command should be the last command listed.
